x + 3
X2 - 8X + 15 = (X - 3)(X - 5)
-16
2(x + 3)(x + 1)

(x + 4)(x +4) or (x + 4)squared
x + 3
x + 5
x*x - 8x +16 = 0 x*x = 8x + 16 x - 16 = _/8x x_/-4 = 2 x = 2
X2 - 8X + 15 = (X - 3)(X - 5)
-16
the answer of √8x+16-3x=0 is x= 0.447213595 = +/- 0.447(to 3 decimal places) if I'm not mistaken
x^2 +8x -9 is equivalent to (x+9)(x-1) when factored
It is 8x + 16
2(x + 3)(x + 1)
(x - 5)(x - 3)
x sq + 8x + 7 = (x + 7) (x + 1)
