Simplifying 4v2 + -3v + -19 = 0 Reorder the terms: -19 + -3v + 4v2 = 0 Solving -19 + -3v + 4v2 = 0 Solving for variable 'v'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -4.75 + -0.75v + v2 = 0 Move the constant term to the right: Add '4.75' to each side of the equation. -4.75 + -0.75v + 4.75 + v2 = 0 + 4.75 Reorder the terms: -4.75 + 4.75 + -0.75v + v2 = 0 + 4.75 Combine like terms: -4.75 + 4.75 = 0.00 0.00 + -0.75v + v2 = 0 + 4.75 -0.75v + v2 = 0 + 4.75 Combine like terms: 0 + 4.75 = 4.75 -0.75v + v2 = 4.75 The v term is -0.75v. Take half its coefficient (-0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. -0.75v + 0.140625 + v2 = 4.75 + 0.140625 Reorder the terms: 0.140625 + -0.75v + v2 = 4.75 + 0.140625 Combine like terms: 4.75 + 0.140625 = 4.890625 0.140625 + -0.75v + v2 = 4.890625 Factor a perfect square on the left side: (v + -0.375)(v + -0.375) = 4.890625 Calculate the square root of the right side: 2.211475752 Break this problem into two subproblems by setting (v + -0.375) equal to 2.211475752 and -2.211475752.Subproblem 1
v + -0.375 = 2.211475752 Simplifying v + -0.375 = 2.211475752 Reorder the terms: -0.375 + v = 2.211475752 Solving -0.375 + v = 2.211475752 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '0.375' to each side of the equation. -0.375 + 0.375 + v = 2.211475752 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + v = 2.211475752 + 0.375 v = 2.211475752 + 0.375 Combine like terms: 2.211475752 + 0.375 = 2.586475752 v = 2.586475752 Simplifying v = 2.586475752Subproblem 2
v + -0.375 = -2.211475752 Simplifying v + -0.375 = -2.211475752 Reorder the terms: -0.375 + v = -2.211475752 Solving -0.375 + v = -2.211475752 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '0.375' to each side of the equation. -0.375 + 0.375 + v = -2.211475752 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + v = -2.211475752 + 0.375 v = -2.211475752 + 0.375 Combine like terms: -2.211475752 + 0.375 = -1.836475752 v = -1.836475752 Simplifying v = -1.836475752Solution
