Solution for x(3x-3)+x(6x-3)=(9x+4)(x-2) equation:


Simplifying
x(3x + -3) + x(6x + -3) = (9x + 4)(x + -2)

Reorder the terms:
x(-3 + 3x) + x(6x + -3) = (9x + 4)(x + -2)
(-3 * x + 3x * x) + x(6x + -3) = (9x + 4)(x + -2)
(-3x + 3x2) + x(6x + -3) = (9x + 4)(x + -2)

Reorder the terms:
-3x + 3x2 + x(-3 + 6x) = (9x + 4)(x + -2)
-3x + 3x2 + (-3 * x + 6x * x) = (9x + 4)(x + -2)
-3x + 3x2 + (-3x + 6x2) = (9x + 4)(x + -2)

Reorder the terms:
-3x + -3x + 3x2 + 6x2 = (9x + 4)(x + -2)

Combine like terms: -3x + -3x = -6x
-6x + 3x2 + 6x2 = (9x + 4)(x + -2)

Combine like terms: 3x2 + 6x2 = 9x2
-6x + 9x2 = (9x + 4)(x + -2)

Reorder the terms:
-6x + 9x2 = (4 + 9x)(x + -2)

Reorder the terms:
-6x + 9x2 = (4 + 9x)(-2 + x)

Multiply (4 + 9x) * (-2 + x)
-6x + 9x2 = (4(-2 + x) + 9x * (-2 + x))
-6x + 9x2 = ((-2 * 4 + x * 4) + 9x * (-2 + x))
-6x + 9x2 = ((-8 + 4x) + 9x * (-2 + x))
-6x + 9x2 = (-8 + 4x + (-2 * 9x + x * 9x))
-6x + 9x2 = (-8 + 4x + (-18x + 9x2))

Combine like terms: 4x + -18x = -14x
-6x + 9x2 = (-8 + -14x + 9x2)

Add '-9x2' to each side of the equation.
-6x + 9x2 + -9x2 = -8 + -14x + 9x2 + -9x2

Combine like terms: 9x2 + -9x2 = 0
-6x + 0 = -8 + -14x + 9x2 + -9x2
-6x = -8 + -14x + 9x2 + -9x2

Combine like terms: 9x2 + -9x2 = 0
-6x = -8 + -14x + 0
-6x = -8 + -14x

Solving
-6x = -8 + -14x

Solving for variable 'x'.
