It is: x(x+7) when factorized
-13
x=(x-1) because when you multiply it out you get x*x and x*1
x2+x x(x+1)
3x2+x-2 = (3x-2)(x+1) when factored
Sorry wasnt allowed to use punctuation. I mean 3X*2 - 15
If you mean: 5 = 2x+15 then x = -5
30 2 x 15 = 30 30 2 x 15 = 30
To factorize ( x^2 - 49 ), you can recognize it as a difference of squares. It can be expressed as ( (x - 7)(x + 7) ), since ( 49 ) is ( 7^2 ). Therefore, the complete factorization is ( (x - 7)(x + 7) ).
7 - x is in its simplest form.
(x + 4)(x + 2)
2(3 - x)(3 + x)
