Simplifying (v2 + 10v + 21)(2v + -2) = 0 Reorder the terms: (21 + 10v + v2)(2v + -2) = 0 Reorder the terms: (21 + 10v + v2)(-2 + 2v) = 0 Multiply (21 + 10v + v2) * (-2 + 2v) (21(-2 + 2v) + 10v * (-2 + 2v) + v2(-2 + 2v)) = 0 ((-2 * 21 + 2v * 21) + 10v * (-2 + 2v) + v2(-2 + 2v)) = 0 ((-42 + 42v) + 10v * (-2 + 2v) + v2(-2 + 2v)) = 0 (-42 + 42v + (-2 * 10v + 2v * 10v) + v2(-2 + 2v)) = 0 (-42 + 42v + (-20v + 20v2) + v2(-2 + 2v)) = 0 (-42 + 42v + -20v + 20v2 + (-2 * v2 + 2v * v2)) = 0 (-42 + 42v + -20v + 20v2 + (-2v2 + 2v3)) = 0 Combine like terms: 42v + -20v = 22v (-42 + 22v + 20v2 + -2v2 + 2v3) = 0 Combine like terms: 20v2 + -2v2 = 18v2 (-42 + 22v + 18v2 + 2v3) = 0 Solving -42 + 22v + 18v2 + 2v3 = 0 Solving for variable 'v'. Factor out the Greatest Common Factor (GCF), '2'. 2(-21 + 11v + 9v2 + v3) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-21 + 11v + 9v2 + v3)' equal to zero and attempt to solve: Simplifying -21 + 11v + 9v2 + v3 = 0 Solving -21 + 11v + 9v2 + v3 = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
