Simplifying v2 + -7vy + -18y2 = 0 Reorder the terms: -7vy + v2 + -18y2 = 0 Solving -7vy + v2 + -18y2 = 0 Solving for variable 'v'. Factor a trinomial. (v + -9y)(v + 2y) = 0Subproblem 1
Set the factor '(v + -9y)' equal to zero and attempt to solve: Simplifying v + -9y = 0 Solving v + -9y = 0 Move all terms containing v to the left, all other terms to the right. Add '9y' to each side of the equation. v + -9y + 9y = 0 + 9y Combine like terms: -9y + 9y = 0 v + 0 = 0 + 9y v = 0 + 9y Remove the zero: v = 9y Simplifying v = 9ySubproblem 2
Set the factor '(v + 2y)' equal to zero and attempt to solve: Simplifying v + 2y = 0 Solving v + 2y = 0 Move all terms containing v to the left, all other terms to the right. Add '-2y' to each side of the equation. v + 2y + -2y = 0 + -2y Combine like terms: 2y + -2y = 0 v + 0 = 0 + -2y v = 0 + -2y Remove the zero: v = -2y Simplifying v = -2ySolution
v = {9y, -2y}
