Simplifying 4t2 + -17t + -1 = 0 Reorder the terms: -1 + -17t + 4t2 = 0 Solving -1 + -17t + 4t2 = 0 Solving for variable 't'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -0.25 + -4.25t + t2 = 0 Move the constant term to the right: Add '0.25' to each side of the equation. -0.25 + -4.25t + 0.25 + t2 = 0 + 0.25 Reorder the terms: -0.25 + 0.25 + -4.25t + t2 = 0 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + -4.25t + t2 = 0 + 0.25 -4.25t + t2 = 0 + 0.25 Combine like terms: 0 + 0.25 = 0.25 -4.25t + t2 = 0.25 The t term is -4.25t. Take half its coefficient (-2.125). Square it (4.515625) and add it to both sides. Add '4.515625' to each side of the equation. -4.25t + 4.515625 + t2 = 0.25 + 4.515625 Reorder the terms: 4.515625 + -4.25t + t2 = 0.25 + 4.515625 Combine like terms: 0.25 + 4.515625 = 4.765625 4.515625 + -4.25t + t2 = 4.765625 Factor a perfect square on the left side: (t + -2.125)(t + -2.125) = 4.765625 Calculate the square root of the right side: 2.18303115 Break this problem into two subproblems by setting (t + -2.125) equal to 2.18303115 and -2.18303115.Subproblem 1
t + -2.125 = 2.18303115 Simplifying t + -2.125 = 2.18303115 Reorder the terms: -2.125 + t = 2.18303115 Solving -2.125 + t = 2.18303115 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '2.125' to each side of the equation. -2.125 + 2.125 + t = 2.18303115 + 2.125 Combine like terms: -2.125 + 2.125 = 0.000 0.000 + t = 2.18303115 + 2.125 t = 2.18303115 + 2.125 Combine like terms: 2.18303115 + 2.125 = 4.30803115 t = 4.30803115 Simplifying t = 4.30803115Subproblem 2
t + -2.125 = -2.18303115 Simplifying t + -2.125 = -2.18303115 Reorder the terms: -2.125 + t = -2.18303115 Solving -2.125 + t = -2.18303115 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '2.125' to each side of the equation. -2.125 + 2.125 + t = -2.18303115 + 2.125 Combine like terms: -2.125 + 2.125 = 0.000 0.000 + t = -2.18303115 + 2.125 t = -2.18303115 + 2.125 Combine like terms: -2.18303115 + 2.125 = -0.05803115 t = -0.05803115 Simplifying t = -0.05803115Solution
