Simplifying -16t2 + 24t + 60 = 0 Reorder the terms: 60 + 24t + -16t2 = 0 Solving 60 + 24t + -16t2 = 0 Solving for variable 't'. Factor out the Greatest Common Factor (GCF), '4'. 4(15 + 6t + -4t2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(15 + 6t + -4t2)' equal to zero and attempt to solve: Simplifying 15 + 6t + -4t2 = 0 Solving 15 + 6t + -4t2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -3.75 + -1.5t + t2 = 0 Move the constant term to the right: Add '3.75' to each side of the equation. -3.75 + -1.5t + 3.75 + t2 = 0 + 3.75 Reorder the terms: -3.75 + 3.75 + -1.5t + t2 = 0 + 3.75 Combine like terms: -3.75 + 3.75 = 0.00 0.00 + -1.5t + t2 = 0 + 3.75 -1.5t + t2 = 0 + 3.75 Combine like terms: 0 + 3.75 = 3.75 -1.5t + t2 = 3.75 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 = 3.75 + 0.5625 Reorder the terms: 0.5625 + -1.5t + t2 = 3.75 + 0.5625 Combine like terms: 3.75 + 0.5625 = 4.3125 0.5625 + -1.5t + t2 = 4.3125 Factor a perfect square on the left side: (t + -0.75)(t + -0.75) = 4.3125 Calculate the square root of the right side: 2.076655966 Break this problem into two subproblems by setting (t + -0.75) equal to 2.076655966 and -2.076655966.Subproblem 1
t + -0.75 = 2.076655966 Simplifying t + -0.75 = 2.076655966 Reorder the terms: -0.75 + t = 2.076655966 Solving -0.75 + t = 2.076655966 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 = 2.076655966 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + t = 2.076655966 + 0.75 t = 2.076655966 + 0.75 Combine like terms: 2.076655966 + 0.75 = 2.826655966 t = 2.826655966 Simplifying t = 2.826655966Subproblem 2
t + -0.75 = -2.076655966 Simplifying t + -0.75 = -2.076655966 Reorder the terms: -0.75 + t = -2.076655966 Solving -0.75 + t = -2.076655966 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 = -2.076655966 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + t = -2.076655966 + 0.75 t = -2.076655966 + 0.75 Combine like terms: -2.076655966 + 0.75 = -1.326655966 t = -1.326655966 Simplifying t = -1.326655966Solution
