(2x + 1)(4x - 7)
(4x - 7)*(2x + 1)

2x^8 -16x^7 +10x^6 = 2x^6(x^2 - 8x + 5)
4x+7-8x=17-4x+7=17-4x=10x = -5/2
7-3(4-2x)-10x 4(4)-2x)-10x 16-8x-10 16-18x
If that was - 10x + 21, it would factor to (x - 3)(x - 7) If that was + 10x + 21, it would factor to (x + 3)(x + 7) As it is, the solutions are irrational.

If that's + 10x + 21, the answer is (x + 7)(x + 3)
(x - 7)(x - 3)
This is not factor-able.
(5x - 7)(x + 3)
This is not right as 10x7 is 70 and 8x13 is 104 the equals means they should both have the same answer. hope this helps ;)
(x - 7)(x - 3)
