-2x3 + 2x2 + 12x =(-2x) (x2 - x - 6) =(-2x) (x+2) (x-3)
x2-12x+36 = (x-6)2
Factor. X^2 + 12X X(X + 12) = 0 X = 0 ------------- X + 12 = 0 X = - 12 --------------
Think of this a 12 x-rays + 5 x-rays Makes 17 x-rays. 12x+5x=17x
5x-8 + 7x 12x-8 12x = 8 x = 8/12 x= 2/3
It is x^2 + 12x or x(x + 12).
x + 12x + 20 = (x + 10)(x + 2)
x2 + 12x + 27 = (x + 9)(x + 3)
If you mean: x^2 +12x +20 then it is (x+2)(x+10) when factored
6x³ +12x + 18 = 6(x + 1)(x² - x + 3)
It is: 12x
x2+12x+28Improved Answer:--x2+12x+28 = (-x+14)(x+2) when factored
x2 + 12x + 32 = (x + 8)(x + 4)
x2+12x+11=0 (x+11)(x+1)=0 x=-11 or x=-1
x2 + 12x + 32 = (x + 4)(x + 8)
I would do this. Multiply through by -1 -1 ( -X^2 +12X +28 ) = X^2 -12X -28 (X+2)(X-14)
12x = x + 3 11x = 3 x = 3/11
