Simplifying v2 + 8v + -16 = -7 Reorder the terms: -16 + 8v + v2 = -7 Solving -16 + 8v + v2 = -7 Solving for variable 'v'. Reorder the terms: -16 + 7 + 8v + v2 = -7 + 7 Combine like terms: -16 + 7 = -9 -9 + 8v + v2 = -7 + 7 Combine like terms: -7 + 7 = 0 -9 + 8v + v2 = 0 Factor a trinomial. (-9 + -1v)(1 + -1v) = 0Subproblem 1
Set the factor '(-9 + -1v)' equal to zero and attempt to solve: Simplifying -9 + -1v = 0 Solving -9 + -1v = 0 Move all terms containing v to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + -1v = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -1v = 0 + 9 -1v = 0 + 9 Combine like terms: 0 + 9 = 9 -1v = 9 Divide each side by '-1'. v = -9 Simplifying v = -9Subproblem 2
Set the factor '(1 + -1v)' equal to zero and attempt to solve: Simplifying 1 + -1v = 0 Solving 1 + -1v = 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 + -1v = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1v = 0 + -1 -1v = 0 + -1 Combine like terms: 0 + -1 = -1 -1v = -1 Divide each side by '-1'. v = 1 Simplifying v = 1Solution
v = {-9, 1}
