Simplifying 0 = 8x2 + 8xy + 2y2 Reorder the terms: 0 = 8xy + 8x2 + 2y2 Solving 0 = 8xy + 8x2 + 2y2 Solving for variable 'x'. Remove the zero: -8xy + -8x2 + -2y2 = 8xy + 8x2 + 2y2 + -8xy + -8x2 + -2y2 Reorder the terms: -8xy + -8x2 + -2y2 = 8xy + -8xy + 8x2 + -8x2 + 2y2 + -2y2 Combine like terms: 8xy + -8xy = 0 -8xy + -8x2 + -2y2 = 0 + 8x2 + -8x2 + 2y2 + -2y2 -8xy + -8x2 + -2y2 = 8x2 + -8x2 + 2y2 + -2y2 Combine like terms: 8x2 + -8x2 = 0 -8xy + -8x2 + -2y2 = 0 + 2y2 + -2y2 -8xy + -8x2 + -2y2 = 2y2 + -2y2 Combine like terms: 2y2 + -2y2 = 0 -8xy + -8x2 + -2y2 = 0 Factor out the Greatest Common Factor (GCF), '-2'. -2(4xy + 4x2 + y2) = 0 Factor a trinomial. -2((2x + y)(2x + y)) = 0 Ignore the factor -2.Subproblem 1
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 = -0.5ySubproblem 2
