x2 - 12x + 36 = (x - 6)2
x2+12x+11=0 (x+11)(x+1)=0 x=-11 or x=-1
-x2 + 2x + 48 = (-x - 6)(x - 8)
(x + 1)(x + 5)
x² + 8x + 15 = (x + 5)(x + 3)
x2+12x+28Improved Answer:--x2+12x+28 = (-x+14)(x+2) when factored
x + 12x + 20 = (x + 10)(x + 2)
3x(x2 + 2x - 4)
-2x3 + 2x2 + 12x =(-2x) (x2 - x - 6) =(-2x) (x+2) (x-3)
(-2x3 - 2x2 + 12x) = -2x (x2 + x - 6) = -2x (x + 3) (x - 2)
x2+12x+5 = 3 x2+12x+5-3 = 0 x2+12x+2 = 0
x2-12x+36 = (x-6)2
-(x - 14)(x + 2)
x2 + 12x + 32 = (x + 8)(x + 4)
-2x3 + 2x2 + 12x = -2x(x2 - x - 6) = -2x(x2 + 2x - 3x - 6) = -2x[ x(x + 2) - 3(x + 2) ] = -2x(x - 3)(x + 2)
x2 + 12x + 32 = (x + 4)(x + 8)
3x3+12x = 3x(x2+4)
