Simplifying 16v2 + 17v + -45 = 0 Reorder the terms: -45 + 17v + 16v2 = 0 Solving -45 + 17v + 16v2 = 0 Solving for variable 'v'. Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. -2.8125 + 1.0625v + v2 = 0 Move the constant term to the right: Add '2.8125' to each side of the equation. -2.8125 + 1.0625v + 2.8125 + v2 = 0 + 2.8125 Reorder the terms: -2.8125 + 2.8125 + 1.0625v + v2 = 0 + 2.8125 Combine like terms: -2.8125 + 2.8125 = 0.0000 0.0000 + 1.0625v + v2 = 0 + 2.8125 1.0625v + v2 = 0 + 2.8125 Combine like terms: 0 + 2.8125 = 2.8125 1.0625v + v2 = 2.8125 The v term is 1.0625v. Take half its coefficient (0.53125). Square it (0.2822265625) and add it to both sides. Add '0.2822265625' to each side of the equation. 1.0625v + 0.2822265625 + v2 = 2.8125 + 0.2822265625 Reorder the terms: 0.2822265625 + 1.0625v + v2 = 2.8125 + 0.2822265625 Combine like terms: 2.8125 + 0.2822265625 = 3.0947265625 0.2822265625 + 1.0625v + v2 = 3.0947265625 Factor a perfect square on the left side: (v + 0.53125)(v + 0.53125) = 3.0947265625 Calculate the square root of the right side: 1.759183493 Break this problem into two subproblems by setting (v + 0.53125) equal to 1.759183493 and -1.759183493.Subproblem 1
v + 0.53125 = 1.759183493 Simplifying v + 0.53125 = 1.759183493 Reorder the terms: 0.53125 + v = 1.759183493 Solving 0.53125 + v = 1.759183493 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '-0.53125' to each side of the equation. 0.53125 + -0.53125 + v = 1.759183493 + -0.53125 Combine like terms: 0.53125 + -0.53125 = 0.00000 0.00000 + v = 1.759183493 + -0.53125 v = 1.759183493 + -0.53125 Combine like terms: 1.759183493 + -0.53125 = 1.227933493 v = 1.227933493 Simplifying v = 1.227933493Subproblem 2
v + 0.53125 = -1.759183493 Simplifying v + 0.53125 = -1.759183493 Reorder the terms: 0.53125 + v = -1.759183493 Solving 0.53125 + v = -1.759183493 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right.
