(x+6)(2x+1)=

Solution for (x+6)(2x+1)= equation:

Simplifying
(x + 6)(2x + 1) = 0

Reorder the terms:
(6 + x)(2x + 1) = 0

Reorder the terms:
(6 + x)(1 + 2x) = 0

Multiply (6 + x) * (1 + 2x)
(6(1 + 2x) + x(1 + 2x)) = 0
((1 * 6 + 2x * 6) + x(1 + 2x)) = 0
((6 + 12x) + x(1 + 2x)) = 0
(6 + 12x + (1 * x + 2x * x)) = 0
(6 + 12x + (1x + 2x2)) = 0

Combine like terms: 12x + 1x = 13x
(6 + 13x + 2x2) = 0

Solving
