Simplifying v2 + 10v = 5 Reorder the terms: 10v + v2 = 5 Solving 10v + v2 = 5 Solving for variable 'v'. Reorder the terms: -5 + 10v + v2 = 5 + -5 Combine like terms: 5 + -5 = 0 -5 + 10v + v2 = 0 Begin completing the square. Move the constant term to the right: Add '5' to each side of the equation. -5 + 10v + 5 + v2 = 0 + 5 Reorder the terms: -5 + 5 + 10v + v2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + 10v + v2 = 0 + 5 10v + v2 = 0 + 5 Combine like terms: 0 + 5 = 5 10v + v2 = 5 The v term is 10v. Take half its coefficient (5). Square it (25) and add it to both sides. Add '25' to each side of the equation. 10v + 25 + v2 = 5 + 25 Reorder the terms: 25 + 10v + v2 = 5 + 25 Combine like terms: 5 + 25 = 30 25 + 10v + v2 = 30 Factor a perfect square on the left side: (v + 5)(v + 5) = 30 Calculate the square root of the right side: 5.477225575 Break this problem into two subproblems by setting (v + 5) equal to 5.477225575 and -5.477225575.Subproblem 1
v + 5 = 5.477225575 Simplifying v + 5 = 5.477225575 Reorder the terms: 5 + v = 5.477225575 Solving 5 + v = 5.477225575 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + v = 5.477225575 + -5 Combine like terms: 5 + -5 = 0 0 + v = 5.477225575 + -5 v = 5.477225575 + -5 Combine like terms: 5.477225575 + -5 = 0.477225575 v = 0.477225575 Simplifying v = 0.477225575Subproblem 2
v + 5 = -5.477225575 Simplifying v + 5 = -5.477225575 Reorder the terms: 5 + v = -5.477225575 Solving 5 + v = -5.477225575 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + v = -5.477225575 + -5 Combine like terms: 5 + -5 = 0 0 + v = -5.477225575 + -5 v = -5.477225575 + -5 Combine like terms: -5.477225575 + -5 = -10.477225575 v = -10.477225575 Simplifying v = -10.477225575Solution
