Simplifying 98v2 + -161v + 56 = 0 Reorder the terms: 56 + -161v + 98v2 = 0 Solving 56 + -161v + 98v2 = 0 Solving for variable 'v'. Factor out the Greatest Common Factor (GCF), '7'. 7(8 + -23v + 14v2) = 0 Factor a trinomial. 7((1 + -2v)(8 + -7v)) = 0 Ignore the factor 7.Subproblem 1
Set the factor '(1 + -2v)' equal to zero and attempt to solve: Simplifying 1 + -2v = 0 Solving 1 + -2v = 0 Move all terms containing v to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -2v = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -2v = 0 + -1 -2v = 0 + -1 Combine like terms: 0 + -1 = -1 -2v = -1 Divide each side by '-2'. v = 0.5 Simplifying v = 0.5Subproblem 2
Set the factor '(8 + -7v)' equal to zero and attempt to solve: Simplifying 8 + -7v = 0 Solving 8 + -7v = 0 Move all terms containing v to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + -7v = 0 + -8 Combine like terms: 8 + -8 = 0 0 + -7v = 0 + -8 -7v = 0 + -8 Combine like terms: 0 + -8 = -8 -7v = -8 Divide each side by '-7'. v = 1.142857143 Simplifying v = 1.142857143Solution
v = {0.5, 1.142857143}
