hcf(6x², 8x) = 2x 6x² = 2 × 3 × x² 8x = 2³ × x → hcf = 2 × x = 2x
8x2 + 6x - 9 = 8x2 + 12x - 6x - 9 = 4x(2x + 3) - 3(2x + 3) = (2x + 3)(4x - 3)
2x
The GCF is 2x.
The GCF is 4x.
hcf(6x², 8x) = 2x 6x² = 2 × 3 × x² 8x = 2³ × x → hcf = 2 × x = 2x
-6
They can be simplified to: 6x+2x = 8x
8x^2 + 6x - 5 = 8x^2 + 10x - 4x - 5 = 2x * (4x + 5) - (4x + 5) = (2x -1) * (4x + 5)
(8x - 8) - (6x - 10) = ?8x - 8 - 6x + 10 = ?8x - 6x + 10 - 8 = ?2x + 2 = ?The answer is (2x + 2)
(4x - 3)(2x + 3)
8x2 + 6x - 9 = 8x2 + 12x - 6x - 9 = 4x(2x + 3) - 3(2x + 3) = (2x + 3)(4x - 3)
8x3 + 4x2 + 6x + 3 = 4x2(2x + 1) + 3(2x + 1) = (2x + 1)(4x2 + 3)
6x = 8x+28 6x-8x = 28 -2x = 28 x = -14
6x-20 = 8x 6x-8x = 20 -2x = 20 x = -10
-6x-32 = 2x -6x-2x = 32 -8x = 32 x = -4
8x + 16 = 6x -> 2x + 16 = 0 -> 2x = -16 -> x = -8
