15x2+16x-15 = (3x+5)(5x-3) when factored
(x + 15)(x + 1)
(2x - 5)(2x - 3)
Yes, 15x2=30
-1
(x - 15)(x - 1)
The given expressions can be simplified to: 16x-10
It will be: 6x2 +8x -15
x+15=16x=16-15x=1
15x2 + 2x - 56 = 15x2 + 30x - 28x - 56 = 15x(x + 2) - 28(x + 2) = (15x - 28)(x + 2)
15x2=30
15x2 - 30x -720 = 15(x - 8)(x + 6).
