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


Simplifying
(2x + -3y)(x + 4y) = 0

Multiply (2x + -3y) * (x + 4y)
(2x * (x + 4y) + -3y * (x + 4y)) = 0
((x * 2x + 4y * 2x) + -3y * (x + 4y)) = 0

Reorder the terms:
((8xy + 2x2) + -3y * (x + 4y)) = 0
((8xy + 2x2) + -3y * (x + 4y)) = 0
(8xy + 2x2 + (x * -3y + 4y * -3y)) = 0
(8xy + 2x2 + (-3xy + -12y2)) = 0

Reorder the terms:
(8xy + -3xy + 2x2 + -12y2) = 0
