(6b+1)(2b-4)=

Solution for (6b+1)(2b-4)= equation:

Simplifying
(6b + 1)(2b + -4) = 0

Reorder the terms:
(1 + 6b)(2b + -4) = 0

Reorder the terms:
(1 + 6b)(-4 + 2b) = 0

Multiply (1 + 6b) * (-4 + 2b)
(1(-4 + 2b) + 6b * (-4 + 2b)) = 0
((-4 * 1 + 2b * 1) + 6b * (-4 + 2b)) = 0
((-4 + 2b) + 6b * (-4 + 2b)) = 0
(-4 + 2b + (-4 * 6b + 2b * 6b)) = 0
(-4 + 2b + (-24b + 12b2)) = 0

Combine like terms: 2b + -24b = -22b
(-4 + -22b + 12b2) = 0

Solving
-4 + -22b + 12b2 = 0
