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


Simplifying
(X + 3y)(3y + -1x) = 0

Reorder the terms:
(X + 3y)(-1x + 3y) = 0

Multiply (X + 3y) * (-1x + 3y)
(X(-1x + 3y) + 3y * (-1x + 3y)) = 0
((-1x * X + 3y * X) + 3y * (-1x + 3y)) = 0
((-1xX + 3yX) + 3y * (-1x + 3y)) = 0
(-1xX + 3yX + (-1x * 3y + 3y * 3y)) = 0
(-1xX + 3yX + (-3xy + 9y2)) = 0

Reorder the terms:
(-1xX + -3xy + 3yX + 9y2) = 0
(-1xX + -3xy + 3yX + 9y2) = 0

Solving
-1xX + -3xy + 3yX + 9y2 = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3yX' to each side of the equation.
-1xX + -3xy + 3yX + -3yX + 9y2 = 0 + -3yX

Combine like terms: 3yX + -3yX = 0
-1xX + -3xy + 0 + 9y2 = 0 + -3yX
-1xX + -3xy + 9y2 = 0 + -3yX
Remove the zero:
-1xX + -3xy + 9y2 = -3yX

Add '-9y2' to each side of the equation.
-1xX + -3xy + 9y2 + -9y2 = -3yX + -9y2

Combine like terms: 9y2 + -9y2 = 0
-1xX + -3xy + 0 = -3yX + -9y2
-1xX + -3xy = -3yX + -9y2

Reorder the terms:
-1xX + -3xy + 3yX + 9y2 = -3yX + 3yX + -9y2 + 9y2

Combine like terms: -3yX + 3yX = 0
-1xX + -3xy + 3yX + 9y2 = 0 + -9y2 + 9y2
-1xX + -3xy + 3yX + 9y2 = -9y2 + 9y2

Combine like terms: -9y2 + 9y2 = 0
-1xX + -3xy + 3yX + 9y2 = 0
