Simplifying v2 + 5v + -28 = 0 Reorder the terms: -28 + 5v + v2 = 0 Solving -28 + 5v + v2 = 0 Solving for variable 'v'. Begin completing the square. Move the constant term to the right: Add '28' to each side of the equation. -28 + 5v + 28 + v2 = 0 + 28 Reorder the terms: -28 + 28 + 5v + v2 = 0 + 28 Combine like terms: -28 + 28 = 0 0 + 5v + v2 = 0 + 28 5v + v2 = 0 + 28 Combine like terms: 0 + 28 = 28 5v + v2 = 28 The v term is 5v. Take half its coefficient (2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. 5v + 6.25 + v2 = 28 + 6.25 Reorder the terms: 6.25 + 5v + v2 = 28 + 6.25 Combine like terms: 28 + 6.25 = 34.25 6.25 + 5v + v2 = 34.25 Factor a perfect square on the left side: (v + 2.5)(v + 2.5) = 34.25 Calculate the square root of the right side: 5.852349955 Break this problem into two subproblems by setting (v + 2.5) equal to 5.852349955 and -5.852349955.Subproblem 1
v + 2.5 = 5.852349955 Simplifying v + 2.5 = 5.852349955 Reorder the terms: 2.5 + v = 5.852349955 Solving 2.5 + v = 5.852349955 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + v = 5.852349955 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + v = 5.852349955 + -2.5 v = 5.852349955 + -2.5 Combine like terms: 5.852349955 + -2.5 = 3.352349955 v = 3.352349955 Simplifying v = 3.352349955Subproblem 2
v + 2.5 = -5.852349955 Simplifying v + 2.5 = -5.852349955 Reorder the terms: 2.5 + v = -5.852349955 Solving 2.5 + v = -5.852349955 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + v = -5.852349955 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + v = -5.852349955 + -2.5 v = -5.852349955 + -2.5 Combine like terms: -5.852349955 + -2.5 = -8.352349955 v = -8.352349955 Simplifying v = -8.352349955Solution
The solution to the problem is based on the solutions from the subproblems. v = {3.352349955, -8.352349955}
