Simplifying 2x2 + -11xy + 9y2 = 0 Reorder the terms: -11xy + 2x2 + 9y2 = 0 Solving -11xy + 2x2 + 9y2 = 0 Solving for variable 'x'. Factor a trinomial. (2x + -9y)(x + -1y) = 0Subproblem 1
Set the factor '(2x + -9y)' equal to zero and attempt to solve: Simplifying 2x + -9y = 0 Solving 2x + -9y = 0 Move all terms containing x to the left, all other terms to the right. Add '9y' to each side of the equation. 2x + -9y + 9y = 0 + 9y Combine like terms: -9y + 9y = 0 2x + 0 = 0 + 9y 2x = 0 + 9y Remove the zero: 2x = 9y Divide each side by '2'. x = 4.5y Simplifying x = 4.5ySubproblem 2
Set the factor '(x + -1y)' equal to zero and attempt to solve: Simplifying x + -1y = 0 Solving x + -1y = 0 Move all terms containing x to the left, all other terms to the right. Add 'y' to each side of the equation. x + -1y + y = 0 + y Combine like terms: -1y + y = 0 x + 0 = 0 + y x = 0 + y Remove the zero: x = y Simplifying x = ySolution
x = {4.5y, y}
