8x2 is 16 or 16/2=8
5-8x2-5x2 is equal to -21.
8x2 8x2
(8x2)-(13x-16)= -78
13y2 - 5yx - 8x2 = (y - x)(13y + 8x).
8x2 + 15 + 26x = 8x2 + 26x + 15 = 8x2 + 20x + 6x + 15 = 4x(2x + 5) + 3(2x + 5) = (2x + 5)(4x + 3)
8x2 + 16x + 8 = 0

7Improved Answer:8x2-18x+9 = (4x-3)(2x-3)
8x2+6x-35 = (2x+5)(4x-7) when factored
8x2 + 2x - 1 = 8x2 + 4x - 2x - 1 = 4x(2x + 1) - 1(2x + 1) = (4x - 1)(2x + 1)
