I'm assuming that "x" is a variable. In this case isolate the x.
(2*2)/9 = x. You would get, x = 0.44~
2x2 + 10 = 9x 2x2 - 9x + 10 = 0 (x - 2)(2x - 5) = 0
2x2 - 9x = 18 2x2 - 9x -18 = 0 (2x - 18)(x + 9) x= -9 and 9
2x2 + 10 - 9x = 0 or 2x2 - 9x + 10 = 0 So (x - 2)*(2x - 5) = 0
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
If you mean: 2x2 -9x +4 then it can be factored to (2x-1)(x-4)
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
If: 2x2-9x-5 = 0 Then: (2x+1)(x-5) = 0 Therefore:: x = -1/2 or x = 5
2x2 - 9x + 4 = (2x - 1)(x - 4)
Factors are (2x + 1)(x + 4), making x either -0.5 or -0.25
2x2-9x+4 = (2x-1)(x-4) when factored
2x2 - 9x + 10 = 2x2 - 4x - 5x + 10 = 2x(x - 2) - 5(x - 2) = (x - 2)(2x - 5)
