Solution for (3x+y)(x-6y)= equation: 


Simplifying
(3x + y)(x + -6y) = 0

Multiply (3x + y) * (x + -6y)
(3x * (x + -6y) + y(x + -6y)) = 0
((x * 3x + -6y * 3x) + y(x + -6y)) = 0

Reorder the terms:
((-18xy + 3x2) + y(x + -6y)) = 0
((-18xy + 3x2) + y(x + -6y)) = 0
(-18xy + 3x2 + (x * y + -6y * y)) = 0
(-18xy + 3x2 + (xy + -6y2)) = 0

Reorder the terms:
(-18xy + xy + 3x2 + -6y2) = 0

Combine like terms: -18xy + xy = -17xy
(-17xy + 3x2 + -6y2) = 0

Solving
-17xy + 3x2 + -6y2 = 0

Solving for variable 'x'.
