volunteer	so the best way to explain it is the denominator can never be 0	18,189	54	[]
volunteer	x-3=0 and x+3=0 is not possible thus x cannot equal - or + 3	18,189	55	[]
volunteer	does this make sense	18,189	56	[]
student	Yes	18,189	57	[]
volunteer	okay so going back to the example	18,189	58	[]
student	Could I try this one on my own	18,189	59	[]
volunteer	yes	18,189	60	[]
volunteer	okay so in fx what is b and what is c	18,189	61	[]
student	5x and -14	18,189	62	[]
volunteer	perfect	18,189	63	[]
student	So it needs to add to 5 and multiply to -14	18,189	64	[]
volunteer	add to -5 and multiply to -14	18,189	65	[]
student	Right	18,189	66	[]
volunteer	you have to be careful with those thats how they like to trick you on a test	18,189	67	[]
volunteer	okay you can continue	18,189	68	[]
volunteer	let me know if you have questions	18,189	69	[]
student	Is that right?	18,189	70	[]
volunteer	yes	18,189	71	[]
volunteer	youre doing great	18,189	72	[]
student	Would it be (x+4)(x-4)	18,189	73	[]
volunteer	correct	18,189	74	[]
student	Got it	18,189	75	[]
student	I have nothing to cancel	18,189	76	[]
volunteer	you need one more thing for your final answer	18,189	77	[]
volunteer	that is okay sometimes there wont be anything to cancel out	18,189	78	[]
student	Is that correct	18,189	79	[]
volunteer	so what you have would stay the same and then you would also state the x does not equal + or -4	18,189	80	[]
volunteer	you got it	18,189	81	[]
student	Okay great. Can I try one more	18,189	82	[]
volunteer	sure thing	18,189	83	[]
volunteer	there you go	18,189	84	[]
student	Is that correct?	18,189	85	[]
volunteer	yes	18,189	86	[]
volunteer	Good job	18,189	87	[]
volunteer	great	18,189	88	[]
student	That made it alot easier. Thank you so much	18,189	89	[]
student	Do you have anymore time?	18,189	90	[]
volunteer	no problem im glad i made it easier to understand	18,189	91	[]
volunteer	yes i have a bit more time	18,189	92	[]
volunteer	if you dont mind when we finish our session please leave a positive review for me :)	18,189	93	[]
student	Determine the domain of the function: x-7/4x^2 -3x - 10	18,189	94	[]
student	Of course, you are great	18,189	95	[]
volunteer	thank you! so are you!	18,189	96	[]
volunteer	is it okay if i clear the screen?	18,189	97	[]
student	Give me one moment to put the equation down on my paper	18,189	98	[]
volunteer	okay no problem let me know when it is okay to clear it	18,189	99	[]
student	Done, you can clear	18,189	100	[]
volunteer	the first step is to make the denominator equal to 0	18,189	101	[]
volunteer	do you know the quadratic formula?	18,189	102	[]
student	Maybe	18,189	103	[]
volunteer	this is the formula	18,189	104	[]
volunteer	does it look familiar?	18,189	105	[]
student	Yes a little	18,189	106	[]
volunteer	okay so first lets identify what is a= b= c=	18,189	107	[]
volunteer	so similar to earlier we are going to look at the denominator is step one	18,189	108	[]
volunteer	so A= 4 B= -3 C= -10	18,189	109	[]
volunteer	does that make sense?	18,189	110	[]
student	Yes because it just goes in order, that doesn't change right?	18,189	111	[]
volunteer	correct	18,189	112	[]
student	Okay good	18,189	113	[]
volunteer	easy way to remember even if the did try to change the order	18,189	114	[]
volunteer	is x^2 is always a	18,189	115	[]
volunteer	x is always b	18,189	116	[]
volunteer	and then number with no x is always c	18,189	117	[]
volunteer	okay do you think you are able to condense this down or would you like help?	18,189	118	[]
student	I can try	18,189	119	[]
student	Do we do in the sqaure root first?	18,189	120	[]
volunteer	you can	18,189	121	[]
volunteer	is that meant to be a 4 or 9?	18,189	122	[]
student	4	18,189	123	[]
volunteer	explain how you got 4	18,189	124	[]
student	Sorry I did mean 9 lol, not sure why I wrote 4	18,189	125	[]
volunteer	all good	18,189	126	[]
volunteer	remember the denominator is for the whole equation	18,189	127	[]
student	Now what do we do?	18,189	128	[]
volunteer	we can condense some more	18,189	129	[]
volunteer	also the sign you have next to X is incorrect	18,189	130	[]
volunteer	so -4(4)= -16 X -10 = 160	18,189	131	[]
student	How did you get 13?	18,189	132	[]
volunteer	okay so if we do the square root 169 it is equal to 13	18,189	133	[]
student	Oh wait	18,189	134	[]
student	I know	18,189	135	[]
volunteer	okay	18,189	136	[]
volunteer	so now you must solve for both of the following	18,189	137	[]
volunteer	does this make sense how i set it up?	18,189	138	[]
student	Yes	18,189	139	[]
volunteer	so it can be written this way	18,189	140	[]
volunteer	there is also the way with the infinity signs but idk if you have seen that in class	18,189	141	[]
student	Yes I do, how do I do that	18,189	142	[]
volunteer	so the way you set it up if the left is the most - and as you go across it becomes more postive	18,189	143	[]
volunteer	do you see that or does it make sense?	18,189	144	[]
student	I don't understand	18,189	145	[]
volunteer	- infinity is the most negative	18,189	146	[]
volunteer	then followed by -5/4	18,189	147	[]
volunteer	then -5,4 to positive 2	18,189	148	[]
volunteer	then 2 , positive infinity	18,189	149	[]
student	Why the 2 though?	18,189	150	[]
volunteer	it make sense if you use your graphing calculator to see it	18,189	151	[]
volunteer	we got 2 from earlier	18,189	152	[]
volunteer	will highlight it in pink	18,189	153	[]
