Simplifying (y + -2x)(y + 2x) = 20 Reorder the terms: (-2x + y)(y + 2x) = 20 Reorder the terms: (-2x + y)(2x + y) = 20 Multiply (-2x + y) * (2x + y) (-2x * (2x + y) + y(2x + y)) = 20 ((2x * -2x + y * -2x) + y(2x + y)) = 20 Reorder the terms: ((-2xy + -4x2) + y(2x + y)) = 20 ((-2xy + -4x2) + y(2x + y)) = 20 (-2xy + -4x2 + (2x * y + y * y)) = 20 (-2xy + -4x2 + (2xy + y2)) = 20 Reorder the terms: (-2xy + 2xy + -4x2 + y2) = 20 Combine like terms: -2xy + 2xy = 0 (0 + -4x2 + y2) = 20 (-4x2 + y2) = 20 Solving -4x2 + y2 = 20 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1y2' to each side of the equation. -4x2 + y2 + -1y2 = 20 + -1y2 Combine like terms: y2 + -1y2 = 0 -4x2 + 0 = 20 + -1y2 -4x2 = 20 + -1y2 Divide each side by '-4'. x2 = -5 + 0.25y2 Simplifying x2 = -5 + 0.25y2 Reorder the terms: 5 + x2 + -0.25y2 = -5 + 0.25y2 + 5 + -0.25y2 Reorder the terms: 5 + x2 + -0.25y2 = -5 + 5 + 0.25y2 + -0.25y2 Combine like terms: -5 + 5 = 0 5 + x2 + -0.25y2 = 0 + 0.25y2 + -0.25y2 5 + x2 + -0.25y2 = 0.25y2 + -0.25y2 Combine like terms: 0.25y2 + -0.25y2 = 0.00 5 + x2 + -0.25y2 = 0.00 The solution to this equation could not be determined.
