Solution for (2x+3y)(4x-y)=0 equation:


Simplifying
(2x + 3y)(4x + -1y) = 0

Multiply (2x + 3y) * (4x + -1y)
(2x * (4x + -1y) + 3y * (4x + -1y)) = 0
((4x * 2x + -1y * 2x) + 3y * (4x + -1y)) = 0

Reorder the terms:
((-2xy + 8x2) + 3y * (4x + -1y)) = 0
((-2xy + 8x2) + 3y * (4x + -1y)) = 0
(-2xy + 8x2 + (4x * 3y + -1y * 3y)) = 0
(-2xy + 8x2 + (12xy + -3y2)) = 0

Reorder the terms:
(-2xy + 12xy + 8x2 + -3y2) = 0

Combine like terms: -2xy + 12xy = 10xy
(10xy + 8x2 + -3y2) = 0

Solving
10xy + 8x2 + -3y2 = 0

Solving for variable 'x'.

Factor a trinomial.

Subproblem 1

Set the factor '(4x + -1y)' equal to zero and attempt to solve: Simplifying 4x + -1y = 0 Solving 4x + -1y = 0 Move all terms containing x to the left, all other terms to the right. Add 'y' to each side of the equation. 4x + -1y + y = 0 + y Combine like terms: -1y + y = 0 4x + 0 = 0 + y 4x = 0 + y Remove the zero: 4x = y Divide each side by '4'. x = 0.25y Simplifying x = 0.25y

Subproblem 2

Set the factor '(2x + 3y)' equal to zero and attempt to solve: Simplifying 2x + 3y = 0 Solving 2x + 3y = 0 Move all terms containing x to the left, all other terms to the right. Add '-3y' to each side of the equation. 2x + 3y + -3y = 0 + -3y Combine like terms: 3y + -3y = 0 2x + 0 = 0 + -3y 2x = 0 + -3y Remove the zero: 2x = -3y Divide each side by '2'. x = -1.5y Simplifying x = -1.5y

Solution

x = {0.25y, -1.5y}
