Simplifying 4x2 + -28xy + 13y2 = 0 Reorder the terms: -28xy + 4x2 + 13y2 = 0 Solving -28xy + 4x2 + 13y2 = 0 Solving for variable 'x'. Factor a trinomial. (2x + -13y)(2x + -1y) = 0Subproblem 1
Set the factor '(2x + -13y)' equal to zero and attempt to solve: Simplifying 2x + -13y = 0 Solving 2x + -13y = 0 Move all terms containing x to the left, all other terms to the right. Add '13y' to each side of the equation. 2x + -13y + 13y = 0 + 13y Combine like terms: -13y + 13y = 0 2x + 0 = 0 + 13y 2x = 0 + 13y Remove the zero: 2x = 13y Divide each side by '2'. x = 6.5y Simplifying x = 6.5ySubproblem 2
Set the factor '(2x + -1y)' equal to zero and attempt to solve: Simplifying 2x + -1y = 0 Solving 2x + -1y = 0 Move all terms containing x to the left, all other terms to the right. Add 'y' to each side of the equation. 2x + -1y + y = 0 + y Combine like terms: -1y + y = 0 2x + 0 = 0 + y 2x = 0 + y Remove the zero: 2x = y Divide each side by '2'. x = 0.5y Simplifying x = 0.5ySolution
x = {6.5y, 0.5y}
