Simplifying 6v2 = -252 + 78v Solving 6v2 = -252 + 78v Solving for variable 'v'. Reorder the terms: 252 + -78v + 6v2 = -252 + 78v + 252 + -78v Reorder the terms: 252 + -78v + 6v2 = -252 + 252 + 78v + -78v Combine like terms: -252 + 252 = 0 252 + -78v + 6v2 = 0 + 78v + -78v 252 + -78v + 6v2 = 78v + -78v Combine like terms: 78v + -78v = 0 252 + -78v + 6v2 = 0 Factor out the Greatest Common Factor (GCF), '6'. 6(42 + -13v + v2) = 0 Factor a trinomial. 6((6 + -1v)(7 + -1v)) = 0 Ignore the factor 6.Subproblem 1
Set the factor '(6 + -1v)' equal to zero and attempt to solve: Simplifying 6 + -1v = 0 Solving 6 + -1v = 0 Move all terms containing v to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + -1v = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -1v = 0 + -6 -1v = 0 + -6 Combine like terms: 0 + -6 = -6 -1v = -6 Divide each side by '-1'. v = 6 Simplifying v = 6Subproblem 2
Set the factor '(7 + -1v)' equal to zero and attempt to solve: Simplifying 7 + -1v = 0 Solving 7 + -1v = 0 Move all terms containing v to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + -1v = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -1v = 0 + -7 -1v = 0 + -7 Combine like terms: 0 + -7 = -7 -1v = -7 Divide each side by '-1'. v = 7 Simplifying v = 7Solution
v = {6, 7}
