x - 3
x^2 +8x -9 is equivalent to (x+9)(x-1) when factored
x = ? 42 = x squared minus x
2x times 4x is 8x squared- then that times x is 8x to the power of three.Mathmatically represented as 8x^3
I is -8x^2.
x - 3
x - 5
x=3
(x - 5)(x - 3)
(8x - 3)(8x + 3)
3x2 - 8x = x(3x - 8)
x2 - 8x = x*x - 8*x = x*(x - 8)
x^2 +8x -9 is equivalent to (x+9)(x-1) when factored
(x-3)(3x+1)
X2 - 8X + 15 = (X - 3)(X - 5)
8x2-39x+45 = (8x-15)(x-3) when factored
If: x^2 -8x = -12 then x^2-8x+12 = 0 and so x = 2 or x = 6
