x2 - 3x - 40 = (x - 8) (x + 5)
20x2 - 27x -8 20 * -8 is -160, and -32 and 5 add to -27 20x2 - 32x + 5x - 8 4x(5x-8) + 1(5x-8) (4x + 1)(5x-8)
8
The equation x2 - 5x - 24 = 0 has the two solutions 8 and -3 for x.
m2 - 8m = 0Factor the expression on the left:m (m - 8) = 0If either factor is zero, then the two sides are equal:m - 8 = 0m = 8m = 0
2(x^2 - 8)
It is: (2x+3)(3x-8) when factored
(2x - 1)(5x + 8)
5x lolzz 8)
8x2-10x-3 = (2x-3)(4x+1) when factored
(x + 1)(x - 8)
3x2 + 2x - 8 = 0 is a quadratic equation.
(x+2)(x−4)
(4x-8)(2x+2)
8
(3x + 8)(3x - 8)
(7x + 8)(7x - 9)
