Simplifying x2 + -7xy + -30y2 = 0 Reorder the terms: -7xy + x2 + -30y2 = 0 Solving -7xy + x2 + -30y2 = 0 Solving for variable 'x'. Factor a trinomial. (x + -10y)(x + 3y) = 0Subproblem 1
Set the factor '(x + -10y)' equal to zero and attempt to solve: Simplifying x + -10y = 0 Solving x + -10y = 0 Move all terms containing x to the left, all other terms to the right. Add '10y' to each side of the equation. x + -10y + 10y = 0 + 10y Combine like terms: -10y + 10y = 0 x + 0 = 0 + 10y x = 0 + 10y Remove the zero: x = 10y Simplifying x = 10ySubproblem 2
Set the factor '(x + 3y)' equal to zero and attempt to solve: Simplifying x + 3y = 0 Solving x + 3y = 0 Move all terms containing x to the left, all other terms to the right. Add '-3y' to each side of the equation. x + 3y + -3y = 0 + -3y Combine like terms: 3y + -3y = 0 x + 0 = 0 + -3y x = 0 + -3y Remove the zero: x = -3y Simplifying x = -3ySolution
x = {10y, -3y}
