(5xy + -3)(2xy + 5) = 0

Reorder the terms:
(-3 + 5xy)(2xy + 5) = 0

Reorder the terms:
(-3 + 5xy)(5 + 2xy) = 0

Multiply (-3 + 5xy) * (5 + 2xy)
(-3(5 + 2xy) + 5xy * (5 + 2xy)) = 0
((5 * -3 + 2xy * -3) + 5xy * (5 + 2xy)) = 0
((-15 + -6xy) + 5xy * (5 + 2xy)) = 0
(-15 + -6xy + (5 * 5xy + 2xy * 5xy)) = 0
(-15 + -6xy + (25xy + 10x2y2)) = 0

Combine like terms: -6xy + 25xy = 19xy
(-15 + 19xy + 10x2y2) = 0

Solving
-15 + 19xy + 10x2y2 = 0
