3x squared minus 25x minus 28
(5x - 2y)(5x + 2y)
32 + 25x + 18 = 50 + 25x
25x+1=33x+7 25x=33x+6 -8x=6 x=-8/6 x=-4/3
It's a square factor.25x2-36.5x*5x 6*6Answer: (5x-6)(5x+6)
3x squared minus 25x minus 28
25x + 35x + 9 is 60x + 9, which factors to 3(20x + 3)
25x method 8x4=32-7x=25x?
(5x - 2)(25x^2 + 10x + 4)
(5x - 2y)(5x + 2y)
The GCF is 5x
(11x - 8)(x + 3)
32 + 25x + 18 = 50 + 25x
-4x2 - 32x + x + 8 = 8x2 - 56x : simplify and group the various terms-32x + 56x + x + 8 = 8x2 + 4x225x + 8 = 12x2 : Now present this as a standard quadratic equation.12x2 - 25x - 8 = 0 : Solving for the roots of a quadratic equation gives :-x = [25 ± √(252 + 4x12x8)] ÷ 2x12 = [25 ± √1009] ÷ 24 = [25 ± 31.765] ÷ 24x = 56.765/24 = 2.365 and x = -6.765/24 = -0.282x = 2.365 and -0.282

x^2+25x-100 is not factorable because there are not numbers that when multiplied equal -100 and when added equal 25.
30x2+25x-24x-20 = 30x2+x-20 = (6x+5)(5x-4) when factored
