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


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

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

Reorder the terms:
((4xy + 8x2) + -3y * (2x + y)) = 0
((4xy + 8x2) + -3y * (2x + y)) = 0
(4xy + 8x2 + (2x * -3y + y * -3y)) = 0
(4xy + 8x2 + (-6xy + -3y2)) = 0

Reorder the terms:
(4xy + -6xy + 8x2 + -3y2) = 0

Combine like terms: 4xy + -6xy = -2xy
(-2xy + 8x2 + -3y2) = 0

Solving
-2xy + 8x2 + -3y2 = 0

Subproblem 1

Set the factor '(4x + -3y)' equal to zero and attempt to solve: Simplifying 4x + -3y = 0 Solving 4x + -3y = 0 Move all terms containing x to the left, all other terms to the right. Add '3y' to each side of the equation. 4x + -3y + 3y = 0 + 3y Combine like terms: -3y + 3y = 0 4x + 0 = 0 + 3y 4x = 0 + 3y Remove the zero: 4x = 3y Divide each side by '4'. x = 0.75y Simplifying x = 0.75y

Subproblem 2

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

Solution

x = {0.75y, -0.5y}
