Solution for (x+6y)(8x-y)= equation: 


Simplifying
(x + 6y)(8x + -1y) = 0

Multiply (x + 6y) * (8x + -1y)
(x(8x + -1y) + 6y * (8x + -1y)) = 0
((8x * x + -1y * x) + 6y * (8x + -1y)) = 0

Reorder the terms:
((-1xy + 8x2) + 6y * (8x + -1y)) = 0
((-1xy + 8x2) + 6y * (8x + -1y)) = 0
(-1xy + 8x2 + (8x * 6y + -1y * 6y)) = 0
(-1xy + 8x2 + (48xy + -6y2)) = 0

Reorder the terms:
(-1xy + 48xy + 8x2 + -6y2) = 0

Combine like terms: -1xy + 48xy = 47xy
(47xy + 8x2 + -6y2) = 0

Solving
47xy + 8x2 + -6y2 = 0

Solving for variable 'x'.
