(b+3)(6b-1)=

Solution for (b+3)(6b-1)= equation:

Simplifying
(b + 3)(6b + -1) = 0

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

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

Multiply (3 + b) * (-1 + 6b)
(3(-1 + 6b) + b(-1 + 6b)) = 0
((-1 * 3 + 6b * 3) + b(-1 + 6b)) = 0
((-3 + 18b) + b(-1 + 6b)) = 0
(-3 + 18b + (-1 * b + 6b * b)) = 0
(-3 + 18b + (-1b + 6b2)) = 0

Combine like terms: 18b + -1b = 17b
(-3 + 17b + 6b2) = 0

Solving
-3 + 17b + 6b2 = 0

Solving for variable 'b'.
