Simplifying 4v2 + -10v = 4 Reorder the terms: -10v + 4v2 = 4 Solving -10v + 4v2 = 4 Solving for variable 'v'. Reorder the terms: -4 + -10v + 4v2 = 4 + -4 Combine like terms: 4 + -4 = 0 -4 + -10v + 4v2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-2 + -5v + 2v2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-2 + -5v + 2v2)' equal to zero and attempt to solve: Simplifying -2 + -5v + 2v2 = 0 Solving -2 + -5v + 2v2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -1 + -2.5v + v2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + -2.5v + 1 + v2 = 0 + 1 Reorder the terms: -1 + 1 + -2.5v + v2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -2.5v + v2 = 0 + 1 -2.5v + v2 = 0 + 1 Combine like terms: 0 + 1 = 1 -2.5v + v2 = 1 The v term is -2.5v. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5v + 1.5625 + v2 = 1 + 1.5625 Reorder the terms: 1.5625 + -2.5v + v2 = 1 + 1.5625 Combine like terms: 1 + 1.5625 = 2.5625 1.5625 + -2.5v + v2 = 2.5625 Factor a perfect square on the left side: (v + -1.25)(v + -1.25) = 2.5625 Calculate the square root of the right side: 1.600781059 Break this problem into two subproblems by setting (v + -1.25) equal to 1.600781059 and -1.600781059.Subproblem 1
v + -1.25 = 1.600781059 Simplifying v + -1.25 = 1.600781059 Reorder the terms: -1.25 + v = 1.600781059 Solving -1.25 + v = 1.600781059 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + v = 1.600781059 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + v = 1.600781059 + 1.25 v = 1.600781059 + 1.25 Combine like terms: 1.600781059 + 1.25 = 2.850781059 v = 2.850781059 Simplifying v = 2.850781059Subproblem 2
v + -1.25 = -1.600781059 Simplifying v + -1.25 = -1.600781059 Reorder the terms: -1.25 + v = -1.600781059 Solving -1.25 + v = -1.600781059 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + v = -1.600781059 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + v = -1.600781059 + 1.25 v = -1.600781059 + 1.25 Combine like terms: -1.600781059 + 1.25 = -0.350781059 v = -0.350781059 Simplifying v = -0.350781059Solution
