Simplifying 0 = -4v2 + 19v + 40 Reorder the terms: 0 = 40 + 19v + -4v2 Solving 0 = 40 + 19v + -4v2 Solving for variable 'v'. Combine like terms: 0 + -40 = -40 -40 + -19v + 4v2 = 40 + 19v + -4v2 + -40 + -19v + 4v2 Reorder the terms: -40 + -19v + 4v2 = 40 + -40 + 19v + -19v + -4v2 + 4v2 Combine like terms: 40 + -40 = 0 -40 + -19v + 4v2 = 0 + 19v + -19v + -4v2 + 4v2 -40 + -19v + 4v2 = 19v + -19v + -4v2 + 4v2 Combine like terms: 19v + -19v = 0 -40 + -19v + 4v2 = 0 + -4v2 + 4v2 -40 + -19v + 4v2 = -4v2 + 4v2 Combine like terms: -4v2 + 4v2 = 0 -40 + -19v + 4v2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -10 + -4.75v + v2 = 0 Move the constant term to the right: Add '10' to each side of the equation. -10 + -4.75v + 10 + v2 = 0 + 10 Reorder the terms: -10 + 10 + -4.75v + v2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + -4.75v + v2 = 0 + 10 -4.75v + v2 = 0 + 10 Combine like terms: 0 + 10 = 10 -4.75v + v2 = 10 The v term is -4.75v. Take half its coefficient (-2.375). Square it (5.640625) and add it to both sides. Add '5.640625' to each side of the equation. -4.75v + 5.640625 + v2 = 10 + 5.640625 Reorder the terms: 5.640625 + -4.75v + v2 = 10 + 5.640625 Combine like terms: 10 + 5.640625 = 15.640625 5.640625 + -4.75v + v2 = 15.640625 Factor a perfect square on the left side: (v + -2.375)(v + -2.375) = 15.640625 Calculate the square root of the right side: 3.954823005 Break this problem into two subproblems by setting (v + -2.375) equal to 3.954823005 and -3.954823005.Subproblem 1
v + -2.375 = 3.954823005 Simplifying v + -2.375 = 3.954823005 Reorder the terms: -2.375 + v = 3.954823005 Solving -2.375 + v = 3.954823005 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '2.375' to each side of the equation. -2.375 + 2.375 + v = 3.954823005 + 2.375 Combine like terms: -2.375 + 2.375 = 0.000 0.000 + v = 3.954823005 + 2.375 v = 3.954823005 + 2.375 Combine like terms: 3.954823005 + 2.375 = 6.329823005 v = 6.329823005 Simplifying v = 6.329823005Subproblem 2
v + -2.375 = -3.954823005 Simplifying v + -2.375 = -3.954823005 Reorder the terms: -2.375 + v = -3.954823005 Solving -2.375 + v = -3.954823005 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '2.375' to each side of the equation. -2.375 + 2.375 + v = -3.954823005 + 2.375 Combine like terms: -2.375 + 2.375 = 0.000 0.000 + v = -3.954823005 + 2.375 v = -3.954823005 + 2.375 Combine like terms: -3.954823005 + 2.375 = -1.579823005 v = -1.579823005 Simplifying v = -1.579823005Solution
