Simplifying -16t2 + 24t + -1 = 0 Reorder the terms: -1 + 24t + -16t2 = 0 Solving -1 + 24t + -16t2 = 0 Solving for variable 't'. Begin completing the square. Divide all terms by -16 the coefficient of the squared term: Divide each side by '-16'. 0.0625 + -1.5t + t2 = 0 Move the constant term to the right: Add '-0.0625' to each side of the equation. 0.0625 + -1.5t + -0.0625 + t2 = 0 + -0.0625 Reorder the terms: 0.0625 + -0.0625 + -1.5t + t2 = 0 + -0.0625 Combine like terms: 0.0625 + -0.0625 = 0.0000 0.0000 + -1.5t + t2 = 0 + -0.0625 -1.5t + t2 = 0 + -0.0625 Combine like terms: 0 + -0.0625 = -0.0625 -1.5t + t2 = -0.0625 The t term is -1.5t. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5t + 0.5625 + t2 = -0.0625 + 0.5625 Reorder the terms: 0.5625 + -1.5t + t2 = -0.0625 + 0.5625 Combine like terms: -0.0625 + 0.5625 = 0.5 0.5625 + -1.5t + t2 = 0.5 Factor a perfect square on the left side: (t + -0.75)(t + -0.75) = 0.5 Calculate the square root of the right side: 0.707106781 Break this problem into two subproblems by setting (t + -0.75) equal to 0.707106781 and -0.707106781.Subproblem 1
t + -0.75 = 0.707106781 Simplifying t + -0.75 = 0.707106781 Reorder the terms: -0.75 + t = 0.707106781 Solving -0.75 + t = 0.707106781 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + t = 0.707106781 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + t = 0.707106781 + 0.75 t = 0.707106781 + 0.75 Combine like terms: 0.707106781 + 0.75 = 1.457106781 t = 1.457106781 Simplifying t = 1.457106781Subproblem 2
t + -0.75 = -0.707106781 Simplifying t + -0.75 = -0.707106781 Reorder the terms: -0.75 + t = -0.707106781 Solving -0.75 + t = -0.707106781 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + t = -0.707106781 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + t = -0.707106781 + 0.75 t = -0.707106781 + 0.75 Combine like terms: -0.707106781 + 0.75 = 0.042893219 t = 0.042893219 Simplifying t = 0.042893219Solution
