$x^2-8x+23=(x-p)^2+q$ for all values of x
Find p and q, does this mean I can just use x as anything such as 0?
if so using simultaneous equations I got $-8=p^2-p^2$
What now?

# 18 is divisible by both 2 and 3 . It is also divisible by $2 \times 3=6$. Similarly, a number is divisible by both 4 and 6. Can we say that the number must also be divisible by $4 \times 6=24$ ? If not, give an example to justify your answer.

A one-dimensional row of positive ions, each with charge + Q and separated from its neighbors by a distance d, occupies the right-hand half of the x axis. That is, there is a + Q charge at x = 0, x = + d, x = + 2d, x = + 3d, and so on out to infinity.

# Dividing polynomials by monomials
### Dividing polynomials by monomials
This section will teach us how to divide a polynomial (more than one term) by a monomial (one term only). We will use a model to help us on the division. We will then try to solve the questions without using the model. At the end, we will look ... | {} |

If $a,b,c \in \mathbb{Z}$ and $a^2 - b^2 = c$ then $a = \frac{m+n}{2}, b = \frac{m-n}{2}$ [duplicate]
Let $a,b,c \in \mathbb{Z}$.
Proove that if $a^2 - b^2 = c$ then exists $m,n \in \mathbb{Z}$ which are both even/odd such that

# What is the graph of f(x) = 2x^2 - 3x + 7?
Sep 27, 2014
To graph a quadratic equation we first need to factorise it into a different form.
First we check what the discriminant is equal to
Where $f \left(x\right) = a {x}^{2} + b {x}^{2} + c$
$\Delta$(Discriminant)$= {b}^{2} - 4 a c$
In this case $\Delta$=${3}^{2} ... | {} |

# On a characterization of primitive polynomials over a finite field
Let $K$ be a finite field. Let us define a primitive polynomial as an $f \in K[X]$ s.t. the multiplicative order of $X$ in $K[X]/(f)$ is equal to $|K|^{\deg f} - 1$. I want to show that $f \in K[X]$ is primitive if and only if $f$ is irreducible and ... | {} |
