Simplifying 0 = -16t2 + 64t + 68 Reorder the terms: 0 = 68 + 64t + -16t2 Solving 0 = 68 + 64t + -16t2 Solving for variable 't'. Combine like terms: 0 + -68 = -68 -68 + -64t + 16t2 = 68 + 64t + -16t2 + -68 + -64t + 16t2 Reorder the terms: -68 + -64t + 16t2 = 68 + -68 + 64t + -64t + -16t2 + 16t2 Combine like terms: 68 + -68 = 0 -68 + -64t + 16t2 = 0 + 64t + -64t + -16t2 + 16t2 -68 + -64t + 16t2 = 64t + -64t + -16t2 + 16t2 Combine like terms: 64t + -64t = 0 -68 + -64t + 16t2 = 0 + -16t2 + 16t2 -68 + -64t + 16t2 = -16t2 + 16t2 Combine like terms: -16t2 + 16t2 = 0 -68 + -64t + 16t2 = 0 Factor out the Greatest Common Factor (GCF), '4'. 4(-17 + -16t + 4t2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(-17 + -16t + 4t2)' equal to zero and attempt to solve: Simplifying -17 + -16t + 4t2 = 0 Solving -17 + -16t + 4t2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -4.25 + -4t + t2 = 0 Move the constant term to the right: Add '4.25' to each side of the equation. -4.25 + -4t + 4.25 + t2 = 0 + 4.25 Reorder the terms: -4.25 + 4.25 + -4t + t2 = 0 + 4.25 Combine like terms: -4.25 + 4.25 = 0.00 0.00 + -4t + t2 = 0 + 4.25 -4t + t2 = 0 + 4.25 Combine like terms: 0 + 4.25 = 4.25 -4t + t2 = 4.25 The t term is -4t. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4t + 4 + t2 = 4.25 + 4 Reorder the terms: 4 + -4t + t2 = 4.25 + 4 Combine like terms: 4.25 + 4 = 8.25 4 + -4t + t2 = 8.25 Factor a perfect square on the left side: (t + -2)(t + -2) = 8.25 Calculate the square root of the right side: 2.872281323 Break this problem into two subproblems by setting (t + -2) equal to 2.872281323 and -2.872281323.Subproblem 1
t + -2 = 2.872281323 Simplifying t + -2 = 2.872281323 Reorder the terms: -2 + t = 2.872281323 Solving -2 + t = 2.872281323 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + t = 2.872281323 + 2 Combine like terms: -2 + 2 = 0 0 + t = 2.872281323 + 2 t = 2.872281323 + 2 Combine like terms: 2.872281323 + 2 = 4.872281323 t = 4.872281323 Simplifying t = 4.872281323Subproblem 2
t + -2 = -2.872281323 Simplifying t + -2 = -2.872281323 Reorder the terms: -2 + t = -2.872281323 Solving -2 + t = -2.872281323 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + t = -2.872281323 + 2 Combine like terms: -2 + 2 = 0 0 + t = -2.872281323 + 2 t = -2.872281323 + 2 Combine like terms: -2.872281323 + 2 = -0.872281323 t = -0.872281323 Simplifying t = -0.872281323Solution
