Solution for =(7x+9y-2x)(8x-3x-3y) equation: 


Simplifying
0 = (7x + 9y + -2x)(8x + -3x + -3y)

Reorder the terms:
0 = (7x + -2x + 9y)(8x + -3x + -3y)

Combine like terms: 7x + -2x = 5x
0 = (5x + 9y)(8x + -3x + -3y)

Combine like terms: 8x + -3x = 5x
0 = (5x + 9y)(5x + -3y)

Multiply (5x + 9y) * (5x + -3y)
0 = (5x * (5x + -3y) + 9y * (5x + -3y))
0 = ((5x * 5x + -3y * 5x) + 9y * (5x + -3y))

Reorder the terms:
0 = ((-15xy + 25x2) + 9y * (5x + -3y))
0 = ((-15xy + 25x2) + 9y * (5x + -3y))
0 = (-15xy + 25x2 + (5x * 9y + -3y * 9y))
0 = (-15xy + 25x2 + (45xy + -27y2))
