For question 1
x²-12x+36
An easy and efficient way to remember how to factor is to see the different parts of the polynomial.
If the last number (in this case 36) has the multiples which add up to the middle number (12), then the polynomial is factorable. 36 has the multiples (6,6) which add up to 12.
Now check the symbols, if the symbol before the last number is a +, that means the two factors have the same symbol. Now see the symbol before the middle number. If its a negative, the factors would be minus as well.
x²-12x+36
(x )(x )
(x- )(x- ) Same symbol as (-)12x
(x-6)(x-6) Multiples of the last number (36)
x²-12x+36 = (x-6)(x-6)
IF YOUR SOLVING FOR A THE ANSWER WOULD BE A=X+12
IF YOUR SOLVING FOR X IT WOULD BE X=-12+A

Answer: -6/5</h3>
Explanation:
The blue diagonal line goes through the two points (0,2) and (5,-4). These are shown as the dark blue enlarged points. You can pick any other points you want that are on the diagonal line, though these are the easiest as they stand out the most.
Use the slope formula to find the slope through these points
m = (y2-y1)/(x2-x1)
m = (-4-2)/(5-0)
m = (-6)/(5)
m = -6/5
The negative slope means the line goes downhill as you move from left to right along the diagonal line.
