(x+5)(x-5) , You use difference of two squares to do this. Remember that if the sign in the equation was (+) then you wouldn’t be able to continue factoring. You can only factor equations like these if there is a subtraction sign.

A= 
The answer would be C. This is because the larger the negative numbers get, the less value they have, so -8 would have a greater value than -9.
3x+3y=-3
divide both sides by 3 for ease
x+y=-1
now eliminate x's
multiply that equation by 2 and add to other one
2x+2y=-2
<u>-2x+y=2 +</u>
0x+3y=0
3y=0
y=0
x+y=-1
x+0=-1
x=-1
(x,y)
(-1,0)
