(b+6)(b-4)=

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

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

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

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

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

Combine like terms: 6b + -4b = 2b
(-24 + 2b + b2) = 0

Solving
-24 + 2b + b2 = 0

Solving for variable 'b'.
