(5x - 6)(5x + 6)
(5x - 2)(x - 5)
Factored, that's (x - 6)(5x + 2) x = 6, -2/5
(4+x) (2x-3)
There is a formula for the "difference of squares." In this case, the answer is (5x + 3)(5x - 3)
2x squared minus 5x minus 3 factored is (2x+1)(x-3).
(5x - 2y)(5x + 2y)
2x squared - 5x - 3 = (2x +1)(x -3)
5x(x - 2)
3x2 - 5x2 = -2x2
-x2+2x
(5x - 6)(5x + 6)
5x^2(4x - 5)(5x + 11)
(x - 1)(5x + 7)
(5x - 2)(x - 5)
7x2 -4x -5x2 +2x = 2x2 -2x
The equation x2 - 5x - 24 = 0 has the two solutions 8 and -3 for x.
