I assume you mean 10x - 25x^2 (i.e. to the power of 2, or x squared) If so 10x - 25x^2 = 5x (2 - 5x)
25x method 8x4=32-7x=25x?
its 10x +9y +1z
35
15
225 x6
3x squared minus 25x minus 28
32 + 25x + 18 = 50 + 25x

25X + 30 = 15X subtract 15X from each side 25X - 15X + 30 = 15X - 15X 10X + 30 = 0 subtract 30 from each side 10X + 30 - 30 = 0 - 30 10X = -30 divide both sides integers by 10 (10/10)X = - 30/10 X = - 3 ----------------check in original equation 25(- 3) + 30 = 15(- 3) - 75 + 30 = - 45 - 45 = - 45 ----------------checks
(5x - 2y)(5x + 2y)
25x (square) plus 40 plus 15 equals 680.
