Simplifying 8x2 + -1xy + -7y2 = 0 Reorder the terms: -1xy + 8x2 + -7y2 = 0 Solving -1xy + 8x2 + -7y2 = 0 Solving for variable 'x'. Factor a trinomial. (x + -1y)(8x + 7y) = 0Subproblem 1
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 = ySubproblem 2
Set the factor '(8x + 7y)' equal to zero and attempt to solve: Simplifying 8x + 7y = 0 Solving 8x + 7y = 0 Move all terms containing x to the left, all other terms to the right. Add '-7y' to each side of the equation. 8x + 7y + -7y = 0 + -7y Combine like terms: 7y + -7y = 0 8x + 0 = 0 + -7y 8x = 0 + -7y Remove the zero: 8x = -7y Divide each side by '8'. x = -0.875y Simplifying x = -0.875ySolution
x = {y, -0.875y}
