Simplifying 15x2y2 + 57xy2 + -90y2 = 0 Reorder the terms: 57xy2 + 15x2y2 + -90y2 = 0 Solving 57xy2 + 15x2y2 + -90y2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '3y2'. 3y2(19x + 5x2 + -30) = 0 Factor a trinomial. 3y2((5x + -6)(x + 5)) = 0 Ignore the factor 3.Subproblem 1
Set the factor 'y2' equal to zero and attempt to solve: Simplifying y2 = 0 Solving y2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-1y2' to each side of the equation. y2 + -1y2 = 0 + -1y2 Remove the zero: 0 = -1y2 Simplifying 0 = -1y2 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
Set the factor '(5x + -6)' equal to zero and attempt to solve: Simplifying 5x + -6 = 0 Reorder the terms: -6 + 5x = 0 Solving -6 + 5x = 0 Move all terms containing x to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + 5x = 0 + 6 Combine like terms: -6 + 6 = 0 0 + 5x = 0 + 6 5x = 0 + 6 Combine like terms: 0 + 6 = 6 5x = 6 Divide each side by '5'. x = 1.2 Simplifying x = 1.2Subproblem 3
Set the factor '(x + 5)' equal to zero and attempt to solve: Simplifying x + 5 = 0 Reorder the terms: 5 + x = 0 Solving 5 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + x = 0 + -5 Combine like terms: 5 + -5 = 0 0 + x = 0 + -5 x = 0 + -5 Combine like terms: 0 + -5 = -5 x = -5 Simplifying x = -5Solution
x = {1.2, -5}
