Solution for (4x-2y)(3x+y)= equation:


Simplifying
(4x + -2y)(3x + y) = 0

Multiply (4x + -2y) * (3x + y)
(4x * (3x + y) + -2y * (3x + y)) = 0
((3x * 4x + y * 4x) + -2y * (3x + y)) = 0

Reorder the terms:
((4xy + 12x2) + -2y * (3x + y)) = 0
((4xy + 12x2) + -2y * (3x + y)) = 0
(4xy + 12x2 + (3x * -2y + y * -2y)) = 0
(4xy + 12x2 + (-6xy + -2y2)) = 0

Reorder the terms:
(4xy + -6xy + 12x2 + -2y2) = 0

Combine like terms: 4xy + -6xy = -2xy
(-2xy + 12x2 + -2y2) = 0

Solving
-2xy + 12x2 + -2y2 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '2'.
2(-1xy + 6x2 + -1y2) = 0

Ignore the factor 2.

Subproblem 1

Set the factor '(2x + -1y)' equal to zero and attempt to solve: Simplifying 2x + -1y = 0 Solving 2x + -1y = 0 Move all terms containing x to the left, all other terms to the right. Add 'y' to each side of the equation. 2x + -1y + y = 0 + y Combine like terms: -1y + y = 0 2x + 0 = 0 + y 2x = 0 + y Remove the zero: 2x = y Divide each side by '2'. x = 0.5y Simplifying x = 0.5y

Subproblem 2

Set the factor '(3x + y)' equal to zero and attempt to solve: Simplifying 3x + y = 0 Solving 3x + y = 0 Move all terms containing x to the left, all other terms to the right. Add '-1y' to each side of the equation. 3x + y + -1y = 0 + -1y Combine like terms: y + -1y = 0 3x + 0 = 0 + -1y 3x = 0 + -1y Remove the zero: 3x = -1y Divide each side by '3'. x = -0.3333333333y Simplifying x = -0.3333333333y

Solution

x = {0.5y, -0.3333333333y}
