(8x2)-(13x-16)= -78
13y2 - 5yx - 8x2 = (y - x)(13y + 8x).
8x2 + 16x + 8 = 0
8x2+6x-35 = (2x+5)(4x-7) when factored
You could try dividing both numerator and denominator by 8x2 .
2(4x2 + 6x - 1)
x(x+3)(x+5)
8x2 is 16 or 16/2=8
2(2x + 5)(2x - 5)
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
