2a(a-5)(a+6)=

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

Simplifying
2a(a + -5)(a + 6) = 0

Reorder the terms:
2a(-5 + a)(a + 6) = 0

Reorder the terms:
2a(-5 + a)(6 + a) = 0

Multiply (-5 + a) * (6 + a)
2a(-5(6 + a) + a(6 + a)) = 0
2a((6 * -5 + a * -5) + a(6 + a)) = 0
2a((-30 + -5a) + a(6 + a)) = 0
2a(-30 + -5a + (6 * a + a * a)) = 0
2a(-30 + -5a + (6a + a2)) = 0

Combine like terms: -5a + 6a = 1a
2a(-30 + 1a + a2) = 0
(-30 * 2a + 1a * 2a + a2 * 2a) = 0
(-60a + 2a2 + 2a3) = 0

Solving
-60a + 2a2 + 2a3 = 0
