Simplifying v2 + 16v + -65 = -2 Reorder the terms: -65 + 16v + v2 = -2 Solving -65 + 16v + v2 = -2 Solving for variable 'v'. Reorder the terms: -65 + 2 + 16v + v2 = -2 + 2 Combine like terms: -65 + 2 = -63 -63 + 16v + v2 = -2 + 2 Combine like terms: -2 + 2 = 0 -63 + 16v + v2 = 0 Begin completing the square. Move the constant term to the right: Add '63' to each side of the equation. -63 + 16v + 63 + v2 = 0 + 63 Reorder the terms: -63 + 63 + 16v + v2 = 0 + 63 Combine like terms: -63 + 63 = 0 0 + 16v + v2 = 0 + 63 16v + v2 = 0 + 63 Combine like terms: 0 + 63 = 63 16v + v2 = 63 The v term is 16v. Take half its coefficient (8). Square it (64) and add it to both sides. Add '64' to each side of the equation. 16v + 64 + v2 = 63 + 64 Reorder the terms: 64 + 16v + v2 = 63 + 64 Combine like terms: 63 + 64 = 127 64 + 16v + v2 = 127 Factor a perfect square on the left side: (v + 8)(v + 8) = 127 Calculate the square root of the right side: 11.26942767 Break this problem into two subproblems by setting (v + 8) equal to 11.26942767 and -11.26942767.Subproblem 1
v + 8 = 11.26942767 Simplifying v + 8 = 11.26942767 Reorder the terms: 8 + v = 11.26942767 Solving 8 + v = 11.26942767 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + v = 11.26942767 + -8 Combine like terms: 8 + -8 = 0 0 + v = 11.26942767 + -8 v = 11.26942767 + -8 Combine like terms: 11.26942767 + -8 = 3.26942767 v = 3.26942767 Simplifying v = 3.26942767Subproblem 2
v + 8 = -11.26942767 Simplifying v + 8 = -11.26942767 Reorder the terms: 8 + v = -11.26942767 Solving 8 + v = -11.26942767 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + v = -11.26942767 + -8 Combine like terms: 8 + -8 = 0 0 + v = -11.26942767 + -8 v = -11.26942767 + -8 Combine like terms: -11.26942767 + -8 = -19.26942767 v = -19.26942767 Simplifying v = -19.26942767Solution
The solution to the problem is based on the solutions from the subproblems. v = {3.26942767, -19.26942767}
