Simplifying 7x2 + 6xy + -1y2 = 0 Reorder the terms: 6xy + 7x2 + -1y2 = 0 Solving 6xy + 7x2 + -1y2 = 0 Solving for variable 'x'. Factor a trinomial. (7x + -1y)(x + y) = 0Subproblem 1
Set the factor '(7x + -1y)' equal to zero and attempt to solve: Simplifying 7x + -1y = 0 Solving 7x + -1y = 0 Move all terms containing x to the left, all other terms to the right. Add 'y' to each side of the equation. 7x + -1y + y = 0 + y Combine like terms: -1y + y = 0 7x + 0 = 0 + y 7x = 0 + y Remove the zero: 7x = y Divide each side by '7'. x = 0.1428571429y Simplifying x = 0.1428571429ySubproblem 2
Set the factor '(x + y)' equal to zero and attempt to solve: Simplifying x + y = 0 Solving x + y = 0 Move all terms containing x to the left, all other terms to the right. Add '-1y' to each side of the equation. x + y + -1y = 0 + -1y Combine like terms: y + -1y = 0 x + 0 = 0 + -1y x = 0 + -1y Remove the zero: x = -1y Simplifying x = -1ySolution
x = {0.1428571429y, -1y}
