(2x - 1)(4x + 1)
2(4x - 3)
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
8x-2x+4x=10x
8x + 9.16 = 4x + 16 8x - 4x = 16 - 9.16 4x = 6.84 x= 1.71
(4x-8)(2x+2)
8x + 5z - 4x + 3z + 6 = 8x - 4x + 5z + 3z - 6 = 4x + 8z - 6
8x^2 + 6x - 5 = 8x^2 + 10x - 4x - 5 = 2x * (4x + 5) - (4x + 5) = (2x -1) * (4x + 5)
(2x - 1)(4x + 1)
2(4x - 3)
(4x - 3)(2x + 3)
4x x 2 = 8x
(4x2) (x/4)(8x - 32) =x3(8x - 32) = 8x3(x - 4)
4x^(2) - 8x '4' is common to both '4' & '8' . So tak outr '4'. Hence 4(x^(2) - 2x) Inside the brackets 'x' is common to both 'x^(2) & '2x'. So take out 'x'. Hence 4x(x - 2) Done , fully factored.
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
8x-2x+4x=10x
8x + 9.16 = 4x + 16 8x - 4x = 16 - 9.16 4x = 6.84 x= 1.71
