Simplifying 10v2 + 21v + 8 = 0 Reorder the terms: 8 + 21v + 10v2 = 0 Solving 8 + 21v + 10v2 = 0 Solving for variable 'v'. Factor a trinomial. (8 + 5v)(1 + 2v) = 0Subproblem 1
Set the factor '(8 + 5v)' equal to zero and attempt to solve: Simplifying 8 + 5v = 0 Solving 8 + 5v = 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 + 5v = 0 + -8 Combine like terms: 8 + -8 = 0 0 + 5v = 0 + -8 5v = 0 + -8 Combine like terms: 0 + -8 = -8 5v = -8 Divide each side by '5'. v = -1.6 Simplifying v = -1.6Subproblem 2
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 = -0.5Solution
v = {-1.6, -0.5}
