(5n+3)(2n-1)=

Solution for (5n+3)(2n-1)= equation:

Simplifying
(5n + 3)(2n + -1) = 0

Reorder the terms:
(3 + 5n)(2n + -1) = 0

Reorder the terms:
(3 + 5n)(-1 + 2n) = 0

Multiply (3 + 5n) * (-1 + 2n)
(3(-1 + 2n) + 5n * (-1 + 2n)) = 0
((-1 * 3 + 2n * 3) + 5n * (-1 + 2n)) = 0
((-3 + 6n) + 5n * (-1 + 2n)) = 0
(-3 + 6n + (-1 * 5n + 2n * 5n)) = 0
(-3 + 6n + (-5n + 10n2)) = 0

Combine like terms: 6n + -5n = 1n
(-3 + 1n + 10n2) = 0

Solving
-3 + 1n + 10n2 = 0
