4x + 27x + 18 = 0
31x + 18= 0
31x + 18 - 18= 0 - 18
31x = -18
31x / 31 = -18 / 31
x = -.58
4x + 3 doesn't factor. It is in its simplest form.
2(4x - 3)(x + 3)
20x2 - 27x -8 20 * -8 is -160, and -32 and 5 add to -27 20x2 - 32x + 5x - 8 4x(5x-8) + 1(5x-8) (4x + 1)(5x-8)
20x^2 + 27x + 9 = 0 20x^2 + 15x +12x + 9 = 0 5x(4x + 3) + 3(4x + 3) = 0 (5x + 3)(4x + 3) = 0 So either (5x + 3) = 0 which yields x = -3/5 or (4x + 3) = 0 which yields x = -3/4
4x(10x + 1)
It is: 4x(1+4)
16x2 + 27x - 28 doesn't factor. Applying the quadratic formula, we find two real solutions:(-27 plus or minus the square root of 2521) divided by 32x = 0.725298776329149x = -2.412798776329149
4x + 16 + 1 = 4x + 17 which cannot be factorised.
