(x + 5)(x + 8)
4x2 + 8x + 4 = 4 (x2 + 2x + 1) = 4 (x + 1)2
(x - 5)(x - 3)
Take out the common factor, 3: 3x + 6 = 3(x + 2).
4x2 + 12 = 4(x2 + 3)4x^2 + 8x + 3x + 6 = 4x(x + 2) + 3(x + 2)
5x+1+x-2 = 8x+6 5x+x-8x = 6+2-1 -2x = 7 x = -3.5
2x^2(x - 2)(x - 2)
x2 + 8x + 12 = (x + 6) (x + 2)
x*x - 8x +16 = 0 x*x = 8x + 16 x - 16 = _/8x x_/-4 = 2 x = 2
It is: 8x^2 +68x +32
It is 8x + 16
8x+2=6x+10 8x-6x=10-2 2x=8 x=4 Therefore, x=4.
8x + -2 = 10 8x = 12 x = 1.5
x = 2
ANSWER: -4X2 -8X-4x (x+2)= (-4x * x) + (-4x*2)= -4X2 -8X
x2 + 8x - 20 = (x - 2)(x + 10).
(x + 6)(x + 2)
