If you mean: 20 - 16 + 8 x 2 then it is 20
20/16 = 5/4
8x2 is 16 or 16/2=8
5-8x2-5x2 is equal to -21.
(8x2)-(13x-16)= -78
8x2 8x2
13y2 - 5yx - 8x2 = (y - x)(13y + 8x).
Simplest form
8x2 + 15 + 26x = 8x2 + 26x + 15 = 8x2 + 20x + 6x + 15 = 4x(2x + 5) + 3(2x + 5) = (2x + 5)(4x + 3)
3/7 is in its simplest form.
8x2 + 16x + 8 = 0
