student	But	7,729	742	[]
student	uh	7,729	743	[]
student	this is	7,729	744	[]
student	I	7,729	745	[]
student	I	7,729	746	[]
student	Mm	7,729	747	[]
student	OK, you can leave, sir. Thank you.	7,729	748	[]
volunteer	OK, you're welcome. Have a good day.	7,729	749	[]
student	You too	7,729	750	[]
student	Hello! I’d like to get some practice by solving the problems on this PDF. You might notice a bit of overwriting on it, but I still want to work through it. Here’s the link to the PDF: https://example.com/document.pdf	8,264	0	[ { "pii_type": "URL", "surrogate": "https://example.com/document.pdf", "start": 184, "end": 216 } ]
student	Starting with problem 2 of Obj. 14!	8,264	1	[]
volunteer	Hi Sarah! I can see it, Ill copy it over so we can look at it together.	8,264	2	[ { "pii_type": "PERSON", "surrogate": "Sarah", "start": 3, "end": 8 } ]
student	Ok	8,264	3	[]
student	I need help with solving it kinda	8,264	4	[]
student	Yep #2	8,264	5	[]
student	Sarah	8,264	6	[ { "pii_type": "PERSON", "surrogate": "Sarah", "start": 0, "end": 5 } ]
volunteer	ok so basically we want to factor out the same monomial out of the two parts	8,264	7	[]
student	ok	8,264	8	[]
student	oh find the gcf fo both?	8,264	9	[]
student	?	8,264	10	[]
volunteer	yes	8,264	11	[]
student	75/2 won't work	8,264	12	[]
volunteer	think of it in two parts	8,264	13	[]
student	so the gcf will be	8,264	14	[]
student	y^2	8,264	15	[]
student	and -25	8,264	16	[]
volunteer	can you factor something out of y^2 - 25	8,264	17	[]
volunteer	almost	8,264	18	[]
student	Sarah	8,264	19	[ { "pii_type": "PERSON", "surrogate": "Sarah", "start": 0, "end": 5 } ]
student	(y-5)(y+5)	8,264	20	[]
volunteer	for the first part we can factor out y^2 that is right	8,264	21	[]
student	there	8,264	22	[]
volunteer	yep that looks right	8,264	23	[]
student	Ok now	8,264	24	[]
student	the next one	8,264	25	[]
student	so i distrbute	8,264	26	[]
student	the 2t with that problem	8,264	27	[]
volunteer	yes	8,264	28	[]
student	2t^2+10t	8,264	29	[]
volunteer	and move everything to the left so you have 0 on the right	8,264	30	[]
student	so combine everything	8,264	31	[]
volunteer	yes	8,264	32	[]
student	combine like terms?	8,264	33	[]
volunteer	yes	8,264	34	[]
student	kk	8,264	35	[]
student	i have t^2+13t-2=0	8,264	36	[]
volunteer	can you double check the t^2 term	8,264	37	[]
student	oh its 5t^2	8,264	38	[]
volunteer	can you type out you're working out on the board	8,264	39	[]
volunteer	i'll be able to help better that way	8,264	40	[]
student	kk	8,264	41	[]
volunteer	can you start from where the question starts after you distibute and show me how you moved things over	8,264	42	[]
student	k	8,264	43	[]
student	Can u write bc i write big	8,264	44	[]
student	and ill write how i solved it	8,264	45	[]
volunteer	sure ill write the expression after the distribution	8,264	46	[]
student	kk	8,264	47	[]
volunteer	can you show me what the expression looks like after adding t^2 from both sides	8,264	48	[]
student	yeah so its t^2	8,264	49	[]
student	is this correct	8,264	50	[]
student	2t^2-t^2=1	8,264	51	[]
volunteer	well since we have -t^2 on the right, we have to add t^2 to both sides to get 0	8,264	52	[]
volunteer	you subtracted t^2 which changes the equation	8,264	53	[]
student	wait wiat	8,264	54	[]
student	you said we combine	8,264	55	[]
volunteer	yes i missed saying a step, first we move balance out the equation by moving the terms to the left	8,264	56	[]
volunteer	ill walk you through it	8,264	57	[]
student	ok	8,264	58	[]
volunteer	when we add t^2 to both sides do you see how that turns to 0 on the right side?	8,264	59	[]
student	so we don't combine like terms?	8,264	60	[]
volunteer	we will once everything is on the left	8,264	61	[]
volunteer	after adding t^2 to both sides we get:	8,264	62	[]
volunteer	does that make sense? now we do it for 3t and -3	8,264	63	[]
volunteer	what should we add on the left to get rid of 03?	8,264	64	[]
volunteer	sorry -3?	8,264	65	[]
student	ok i think i get it	8,264	66	[]
student	so basically everything becomes positive	8,264	67	[]
volunteer	not necessairily, the goal of this step is to get 0 on the right so that you can solve it the way you usually do by factoring	8,264	68	[]
volunteer	if like terms are on both sides its just more confusing to solve	8,264	69	[]
volunteer	do you want me to show you the next step? that gets us closer to getting 0 on the right?	8,264	70	[]
volunteer	let me know where i can help	8,264	71	[]
student	nvm I understand it	8,264	72	[]
student	answer is t=-4/3,-1	8,264	73	[]
student	now $4	8,264	74	[]
student	#4	8,264	75	[]
volunteer	yep nice job	8,264	76	[]
volunteer	oops sorry another look made me see that both t's should be positive, double check your signs	8,264	77	[]
volunteer	ill start looking at #4	8,264	78	[]
student	kk	8,264	79	[]
volunteer	can you show me what your first step in doing problem #4 would be	8,264	80	[]
student	yes	8,264	81	[]
student	x= -7,4	8,264	82	[]
volunteer	to balance the equation and get 0 on the right we need to subtract 28 from both sides	8,264	83	[]
volunteer	yep you got it!	8,264	84	[]
student	next one	8,264	85	[]
student	honestly a lot of these problems are not from the notes that we've done w my teacher in class	8,264	86	[]
student	so it feels like im re learning new material	8,264	87	[]
volunteer	that's ok im happy to help, sometime exampled don't translate that well but the same concepts apply	8,264	88	[]
student	kk	8,264	89	[]
volunteer	where do you get stuck with this one?	8,264	90	[]
