Simplifying
(3x + 5y)(5x + -6y) = 0
Multiply (3x + 5y) * (5x + -6y)
(3x * (5x + -6y) + 5y * (5x + -6y)) = 0
((5x * 3x + -6y * 3x) + 5y * (5x + -6y)) = 0
Reorder the terms:
((-18xy + 15x2) + 5y * (5x + -6y)) = 0
((-18xy + 15x2) + 5y * (5x + -6y)) = 0
(-18xy + 15x2 + (5x * 5y + -6y * 5y)) = 0
(-18xy + 15x2 + (25xy + -30y2)) = 0
Reorder the terms:
(-18xy + 25xy + 15x2 + -30y2) = 0
Combine like terms: -18xy + 25xy = 7xy
(7xy + 15x2 + -30y2) = 0
Solving
7xy + 15x2 + -30y2 = 0
Solving for variable 'x'.
Factor a trinomial.
(5x + -6y)(3x + 5y) = 0

Hey there,
Here's your answer:
Question is (3x+5y)(5x-6y)
=> 3x*5x - 3x*6y + 5y*5x - 5y*6y
=> 15x² - 18xy + 25xy - 30y²
=> 15x² +7xy - 30y²
I HOPE IT WILL HELP U
