Solution for A(x)=(x-2)(-3x-9) equation: 


Simplifying
A(x) = (x + -2)(-3x + -9)

Multiply A * x
xA = (x + -2)(-3x + -9)

Reorder the terms:
xA = (-2 + x)(-3x + -9)

Reorder the terms:
xA = (-2 + x)(-9 + -3x)

Multiply (-2 + x) * (-9 + -3x)
xA = (-2(-9 + -3x) + x(-9 + -3x))
xA = ((-9 * -2 + -3x * -2) + x(-9 + -3x))
xA = ((18 + 6x) + x(-9 + -3x))
xA = (18 + 6x + (-9 * x + -3x * x))
xA = (18 + 6x + (-9x + -3x2))

Combine like terms: 6x + -9x = -3x
xA = (18 + -3x + -3x2)

Solving
xA = 18 + -3x + -3x2

Solving for variable 'x'.
