Simplifying v2 + -2v + -50 = -7 Reorder the terms: -50 + -2v + v2 = -7 Solving -50 + -2v + v2 = -7 Solving for variable 'v'. Reorder the terms: -50 + 7 + -2v + v2 = -7 + 7 Combine like terms: -50 + 7 = -43 -43 + -2v + v2 = -7 + 7 Combine like terms: -7 + 7 = 0 -43 + -2v + v2 = 0 Begin completing the square. Move the constant term to the right: Add '43' to each side of the equation. -43 + -2v + 43 + v2 = 0 + 43 Reorder the terms: -43 + 43 + -2v + v2 = 0 + 43 Combine like terms: -43 + 43 = 0 0 + -2v + v2 = 0 + 43 -2v + v2 = 0 + 43 Combine like terms: 0 + 43 = 43 -2v + v2 = 43 The v term is -2v. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2v + 1 + v2 = 43 + 1 Reorder the terms: 1 + -2v + v2 = 43 + 1 Combine like terms: 43 + 1 = 44 1 + -2v + v2 = 44 Factor a perfect square on the left side: (v + -1)(v + -1) = 44 Calculate the square root of the right side: 6.633249581 Break this problem into two subproblems by setting (v + -1) equal to 6.633249581 and -6.633249581.Subproblem 1
v + -1 = 6.633249581 Simplifying v + -1 = 6.633249581 Reorder the terms: -1 + v = 6.633249581 Solving -1 + v = 6.633249581 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + v = 6.633249581 + 1 Combine like terms: -1 + 1 = 0 0 + v = 6.633249581 + 1 v = 6.633249581 + 1 Combine like terms: 6.633249581 + 1 = 7.633249581 v = 7.633249581 Simplifying v = 7.633249581Subproblem 2
v + -1 = -6.633249581 Simplifying v + -1 = -6.633249581 Reorder the terms: -1 + v = -6.633249581 Solving -1 + v = -6.633249581 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + v = -6.633249581 + 1 Combine like terms: -1 + 1 = 0 0 + v = -6.633249581 + 1 v = -6.633249581 + 1 Combine like terms: -6.633249581 + 1 = -5.633249581 v = -5.633249581 Simplifying v = -5.633249581Solution
The solution to the problem is based on the solutions from the subproblems. v = {7.633249581, -5.633249581}
