(5b-4)(b+6)=

Solution for (5b-4)(b+6)= equation:

Simplifying
(5b + -4)(b + 6) = 0

Reorder the terms:
(-4 + 5b)(b + 6) = 0

Reorder the terms:
(-4 + 5b)(6 + b) = 0

Multiply (-4 + 5b) * (6 + b)
(-4(6 + b) + 5b * (6 + b)) = 0
((6 * -4 + b * -4) + 5b * (6 + b)) = 0
((-24 + -4b) + 5b * (6 + b)) = 0
(-24 + -4b + (6 * 5b + b * 5b)) = 0
(-24 + -4b + (30b + 5b2)) = 0
