Solution for (x+y^2)(4x-8y^2)=0 equation:


Simplifying
(x + y2)(4x + -8y2) = 0

Multiply (x + y2) * (4x + -8y2)
(x(4x + -8y2) + y2(4x + -8y2)) = 0
((4x * x + -8y2 * x) + y2(4x + -8y2)) = 0

Reorder the terms:
((-8xy2 + 4x2) + y2(4x + -8y2)) = 0
((-8xy2 + 4x2) + y2(4x + -8y2)) = 0
(-8xy2 + 4x2 + (4x * y2 + -8y2 * y2)) = 0
(-8xy2 + 4x2 + (4xy2 + -8y4)) = 0

Reorder the terms:
(-8xy2 + 4xy2 + 4x2 + -8y4) = 0

Combine like terms: -8xy2 + 4xy2 = -4xy2
(-4xy2 + 4x2 + -8y4) = 0

Solving
-4xy2 + 4x2 + -8y4 = 0

Solving for variable 'x'.

Subproblem 1

Set the factor '(x + -2y2)' equal to zero and attempt to solve: Simplifying x + -2y2 = 0 Solving x + -2y2 = 0 Move all terms containing x to the left, all other terms to the right. Add '2y2' to each side of the equation. x + -2y2 + 2y2 = 0 + 2y2 Combine like terms: -2y2 + 2y2 = 0 x + 0 = 0 + 2y2 x = 0 + 2y2 Remove the zero: x = 2y2 Simplifying x = 2y2

Subproblem 2

Set the factor '(x + y2)' equal to zero and attempt to solve: Simplifying x + y2 = 0 Solving x + y2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-1y2' to each side of the equation. x + y2 + -1y2 = 0 + -1y2 Combine like terms: y2 + -1y2 = 0 x + 0 = 0 + -1y2 x = 0 + -1y2 Remove the zero: x = -1y2 Simplifying x = -1y2

Solution

x = {2y2, -1y2}
