Simplifying
(x + -6)(9x + 2) = -25(x + -6)

Reorder the terms:
(-6 + x)(9x + 2) = -25(x + -6)

Reorder the terms:
(-6 + x)(2 + 9x) = -25(x + -6)

Multiply (-6 + x) * (2 + 9x)
(-6(2 + 9x) + x(2 + 9x)) = -25(x + -6)
((2 * -6 + 9x * -6) + x(2 + 9x)) = -25(x + -6)
((-12 + -54x) + x(2 + 9x)) = -25(x + -6)
(-12 + -54x + (2 * x + 9x * x)) = -25(x + -6)
(-12 + -54x + (2x + 9x2)) = -25(x + -6)

Combine like terms: -54x + 2x = -52x
(-12 + -52x + 9x2) = -25(x + -6)
