There are four solutions to 9x4 plus 27x3 - 4x2 - 12x equals 0. One of the solutions is x = -3.
4x2+50x = 0 4x(x+12.5) = 0 x = 0 or x = -12.5
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
4x2 = -12x, divide both sides by 4x: x = -3
Assuming that 4x2+2x = 0: 2x (2x+1) = 0 2x = 0 or 2x+1 = 0 x = 0 or -1/2
dont know sorry
-((4x + 1)(x - 1))
(2x + 3)(2x + 3)
1/2 , 3/2
4x2 - 2x = 0
sure it does... that would be true
4x2 - 13 x + 3 = 0 (4x - 1)(x - 3) = 0 x = 3, 1/4
