If that's + 4x2, the answer is 2x(x2 + 2x - 4)
(x+6)*(x-4)
x^2 - 8z - 48 Factor ( x - 12)(x + 4)
If that's + 8x, the answer is 4(x2 + 2x - 6) If that's - 8x, the answer is 4(x2 - 2x - 6)
x2 + 11x + 18 (x + 9)(x + 2) CHECK: x2 + 9x + 2x + 18 x2 + 11x + 18 SET EACH EQUAL TO ZERO: x + 9 = 0 x = -9 x + 2 = 0 x = -2 NOW YOU ARE DONE: Solution set: {-9, -2}
x2 + 2x - 48 = x2 + 8x - 6x - 48 = x(x + 8) - 6(x + 8) = (x - 6)(x + 8)
-x2 + 2x + 48 = (-x - 6)(x - 8)
-x2 + 2x + 48 = (-x - 6)(x - 8) = -(x + 6)(x - 8)
-x2 + 2x + 48 = (x +6)(8 - x)
-x2 + 2x + 48 = (-x - 6)(x - 8)
x2 + 2x - 3 = (x + 3)(x - 1)
x2+2x-63 = (x-7)(x+9) when factored
x2 + 2x - 15 = (x + 5)(x - 3)
(2x3 - x2) = x2 (2x - 1)
x2-2x-15 = (x+3)(x-5) when factored
x2-2x-24 when factorised = (x+4)(x-6)
x2 - 2x - 24 = (x - 6)(x + 4)
