Simplifying -16t2 + 52t + 60 = 0 Reorder the terms: 60 + 52t + -16t2 = 0 Solving 60 + 52t + -16t2 = 0 Solving for variable 't'. Factor out the Greatest Common Factor (GCF), '4'. 4(15 + 13t + -4t2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(15 + 13t + -4t2)' equal to zero and attempt to solve: Simplifying 15 + 13t + -4t2 = 0 Solving 15 + 13t + -4t2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -3.75 + -3.25t + t2 = 0 Move the constant term to the right: Add '3.75' to each side of the equation. -3.75 + -3.25t + 3.75 + t2 = 0 + 3.75 Reorder the terms: -3.75 + 3.75 + -3.25t + t2 = 0 + 3.75 Combine like terms: -3.75 + 3.75 = 0.00 0.00 + -3.25t + t2 = 0 + 3.75 -3.25t + t2 = 0 + 3.75 Combine like terms: 0 + 3.75 = 3.75 -3.25t + t2 = 3.75 The t term is -3.25t. Take half its coefficient (-1.625). Square it (2.640625) and add it to both sides. Add '2.640625' to each side of the equation. -3.25t + 2.640625 + t2 = 3.75 + 2.640625 Reorder the terms: 2.640625 + -3.25t + t2 = 3.75 + 2.640625 Combine like terms: 3.75 + 2.640625 = 6.390625 2.640625 + -3.25t + t2 = 6.390625 Factor a perfect square on the left side: (t + -1.625)(t + -1.625) = 6.390625 Calculate the square root of the right side: 2.527968552 Break this problem into two subproblems by setting (t + -1.625) equal to 2.527968552 and -2.527968552.Subproblem 1
t + -1.625 = 2.527968552 Simplifying t + -1.625 = 2.527968552 Reorder the terms: -1.625 + t = 2.527968552 Solving -1.625 + t = 2.527968552 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.625' to each side of the equation. -1.625 + 1.625 + t = 2.527968552 + 1.625 Combine like terms: -1.625 + 1.625 = 0.000 0.000 + t = 2.527968552 + 1.625 t = 2.527968552 + 1.625 Combine like terms: 2.527968552 + 1.625 = 4.152968552 t = 4.152968552 Simplifying t = 4.152968552Subproblem 2
t + -1.625 = -2.527968552 Simplifying t + -1.625 = -2.527968552 Reorder the terms: -1.625 + t = -2.527968552 Solving -1.625 + t = -2.527968552 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.625' to each side of the equation. -1.625 + 1.625 + t = -2.527968552 + 1.625 Combine like terms: -1.625 + 1.625 = 0.000 0.000 + t = -2.527968552 + 1.625 t = -2.527968552 + 1.625 Combine like terms: -2.527968552 + 1.625 = -0.902968552 t = -0.902968552 Simplifying t = -0.902968552Solution
