2(2x-11)(3x+5)
You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve
6 - 3x = 4 - 2x 6 = x + 4 x = 2 Check it. 6 - 6 = 4 - 4 It checks.
Let square = [x] -4+3*(-2)*[-4]+[3x-2x]=-4-6-2+[x]=-12+[x]The answer is negative 12 plus squared x.

3x2 + 2x - 8 = 0 is a quadratic equation.
x(3x - 2)
3x=2x-12x=-12
It is a quadratic equation and its solutions are: x = -3/2 and x = 3
(x + 3)(3x - 2)
5x3 - 3x2 + 2x = x*(5x2 - 3x + 2) The quadratic has no real factors.
(x - 2)(2x + 7)
3X = x2 - 2xsubtract 3X from each sideX2 - 5X = 0factor out an XX(X - 5) = 0=========X = 0--------orX = 5--------
3x - 2x + 4 = 0 3x - 2x = -4 x = -4
3x(2x + 1)
3x+7=2x-5 x=-12
