4x2 -x -1 :D
3x2-4x-4=0 (3x+2)(x-2)+0 x=-3/2, 2
If you meant 3x2 - 5x + 2, here is your answer 3x2 - 5x +2 = 0 => 3x2 - 3x - 2x + 2 = 0 => 3x(x-1) - 2(x-1) = 0 => (3x - 2) (x-1) = 0 => x = 2/3 or, x = 1
4x + 5 < 5x + 3 5 < x + 3 x > 2
5x + 3 = 4xSubtract 3 from each side:5x = 4x - 3Subtract 4x from each side:x = -3
4x2 -x -1 :D
3x2-4x-4=0 (3x+2)(x-2)+0 x=-3/2, 2
4x - 3 - 5x + 7 = 6 4x - 5x = 3 - 7 + 6 -1x = 2 x = -2
If you meant 3x2 - 5x + 2, here is your answer 3x2 - 5x +2 = 0 => 3x2 - 3x - 2x + 2 = 0 => 3x(x-1) - 2(x-1) = 0 => (3x - 2) (x-1) = 0 => x = 2/3 or, x = 1
5x-2x-3x+4x = (5-2-3+4)x = 4x
(5x + 3)(4x^2 + 1)
4x + 5 < 5x + 3 5 < x + 3 x > 2
x3 + 3x2 - 4x -12 x2(x + 3) - 4(x + 3) (x2 - 4)(x+3)
5x + 3 = 4xSubtract 3 from each side:5x = 4x - 3Subtract 4x from each side:x = -3
-1
why don`t you try a calculator buy one if you don`t have one.
5x + 3 - 4 + 4x = 9x -1
