7 - x is in its simplest form.
(x + 4)(x + 2)
2(3 - x)(3 + x)
It is: x(x+7) when factorized
-13
2 x 2 x 3 x 19 = 228
x=(x-1) because when you multiply it out you get x*x and x*1
It is (x-3)(x-4) when factored
2 x 2 x 2 x 2 x 2 = 32
x2+x x(x+1)
I could factorize : (3 + x) (17 + 3 x) But have no idea about the next part...
-2(x + 5)(x - 6)
3x2+x-2 = (3x-2)(x+1) when factored
