If that's +4x, the answer is (x - 4)(x + 8) If that's -4x, the answer is (x + 4)(x - 8)
4x -8 = -4
4x - 3 = 5 4x = 5 + 3 4x = 8 x = 8/4 x = 2
4x - 7 = 1 Therefore, 4x = 8 x = 8/4 x = 2
4x2+4x-8 4(x2+x-2) and (4x+8)(x-1)
8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1
8 + 4x - x = 8 3x = 8 - 8 x = 0
If that's +4x, the answer is (x - 4)(x + 8) If that's -4x, the answer is (x + 4)(x - 8)
8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1
2(4x + 4) = (4x - 12) 8x + 8 = 4x - 12 8x - 4x + 8 = 4x - 4x - 12 4x + 8 = -12 4x + 8 - 8 = -12 - 8 4x = -20 4x/4 = -20/4 x = -5
4x -8 = -4
4x - 3 = 5 4x = 5 + 3 4x = 8 x = 8/4 x = 2
(4x - 1)(4x -1) or (4x - 1)2
If 4x = 8, then x = 2
4x - 7 = 1 Therefore, 4x = 8 x = 8/4 x = 2
