x2 + 8x + 12 = (x + 6) (x + 2)
x + 3
X2 - 8X + 15 = (X - 3)(X - 5)
If -8x+3=251, then 8x=-248. Therefore, x=-31.
(x+4)(x+4), or (x+4)^2.
x² + 8x + 15 = (x + 5)(x + 3)
- 8x + 8x = 0 so question is meaningless.
x2 + 8x + 15 = (x + 3)(x + 5)
x2 + 8x + 15 = (x + 3) (x + 5).
It is 8x + 16
5x+1+x-2 = 8x+6 5x+x-8x = 6+2-1 -2x = 7 x = -3.5
x2 + 8x = x(x+8)
-8x
It is 7+8x simplified
8x + 3 = 35 8x = 32 x = 4
x*x - 8x +16 = 0 x*x = 8x + 16 x - 16 = _/8x x_/-4 = 2 x = 2
8x + 8=40 8x=40-8 8x=32 x=32/8 x=4
