Simplifying 50x2 + -40xy + 8y2 = 0 Reorder the terms: -40xy + 50x2 + 8y2 = 0 Solving -40xy + 50x2 + 8y2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(-20xy + 25x2 + 4y2) = 0 Factor a trinomial. 2((5x + -2y)(5x + -2y)) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(5x + -2y)' equal to zero and attempt to solve: Simplifying 5x + -2y = 0 Solving 5x + -2y = 0 Move all terms containing x to the left, all other terms to the right. Add '2y' to each side of the equation. 5x + -2y + 2y = 0 + 2y Combine like terms: -2y + 2y = 0 5x + 0 = 0 + 2y 5x = 0 + 2y Remove the zero: 5x = 2y Divide each side by '5'. x = 0.4y Simplifying x = 0.4ySubproblem 2
