Answer:
Simplifying
(7x + -4y)(4x + 3y) = 0
Multiply (7x + -4y) * (4x + 3y)
(7x * (4x + 3y) + -4y * (4x + 3y)) = 0
((4x * 7x + 3y * 7x) + -4y * (4x + 3y)) = 0
Reorder the terms:
((21xy + 28x2) + -4y * (4x + 3y)) = 0
((21xy + 28x2) + -4y * (4x + 3y)) = 0
(21xy + 28x2 + (4x * -4y + 3y * -4y)) = 0
(21xy + 28x2 + (-16xy + -12y2)) = 0
Reorder the terms:
(21xy + -16xy + 28x2 + -12y2) = 0
Combine like terms: 21xy + -16xy = 5xy
(5xy + 28x2 + -12y2) = 0
Solving
5xy + 28x2 + -12y2 = 0
Solving for variable 'x'.
Factor a trinomial.
(7x + -4y)(4x + 3y) = 0
