16x-8x+12 = 78+22 16x-8x = 78+22-12 8x = 88 x = 11
-8x -7y
9x2 + 8x - 1 = (9x - 1)(x + 1)
2(4x - 3)(x + 3)
The answer is (2x^2+3)(4x+1)
You don't. There is no way to factorise it.
16x-8x+12 = 78+22 16x-8x = 78+22-12 8x = 88 x = 11
16x + 3
-8x -7y
(4x + 1)(2x + 3)
(8x + 9)(3x^2 - 1)
9x2 + 8x - 1 = (9x - 1)(x + 1)
2(x + 3)(x + 1)
16x - 8x + 12 = 78 + 22 or simplified to (16x-8x=8x)(78+22=100) 8x + 12 = 100 Simplify some more (Subtract 12 from both sides) 8x = 88 Divide both sides by 8, and x = 11
The GCF is 8x.
(4x - 3)(2x + 3)
(x - 5)(x - 3)
