Solution for 6u(5u+2)-3u(3u-3)= equation:


Simplifying
6u(5u + 2) + -3u(3u + -3) = 0

Reorder the terms:
6u(2 + 5u) + -3u(3u + -3) = 0
(2 * 6u + 5u * 6u) + -3u(3u + -3) = 0
(12u + 30u2) + -3u(3u + -3) = 0

Reorder the terms:
12u + 30u2 + -3u(-3 + 3u) = 0
12u + 30u2 + (-3 * -3u + 3u * -3u) = 0
12u + 30u2 + (9u + -9u2) = 0

Reorder the terms:
12u + 9u + 30u2 + -9u2 = 0

Combine like terms: 12u + 9u = 21u
21u + 30u2 + -9u2 = 0
