Simplifying -16t2 + 44t + 8 = 0 Reorder the terms: 8 + 44t + -16t2 = 0 Solving 8 + 44t + -16t2 = 0 Solving for variable 't'. Factor out the Greatest Common Factor (GCF), '4'. 4(2 + 11t + -4t2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(2 + 11t + -4t2)' equal to zero and attempt to solve: Simplifying 2 + 11t + -4t2 = 0 Solving 2 + 11t + -4t2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -0.5 + -2.75t + t2 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + -2.75t + 0.5 + t2 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + -2.75t + t2 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + -2.75t + t2 = 0 + 0.5 -2.75t + t2 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 -2.75t + t2 = 0.5 The t term is -2.75t. Take half its coefficient (-1.375). Square it (1.890625) and add it to both sides. Add '1.890625' to each side of the equation. -2.75t + 1.890625 + t2 = 0.5 + 1.890625 Reorder the terms: 1.890625 + -2.75t + t2 = 0.5 + 1.890625 Combine like terms: 0.5 + 1.890625 = 2.390625 1.890625 + -2.75t + t2 = 2.390625 Factor a perfect square on the left side: (t + -1.375)(t + -1.375) = 2.390625 Calculate the square root of the right side: 1.54616461 Break this problem into two subproblems by setting (t + -1.375) equal to 1.54616461 and -1.54616461.Subproblem 1
t + -1.375 = 1.54616461 Simplifying t + -1.375 = 1.54616461 Reorder the terms: -1.375 + t = 1.54616461 Solving -1.375 + t = 1.54616461 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.375' to each side of the equation. -1.375 + 1.375 + t = 1.54616461 + 1.375 Combine like terms: -1.375 + 1.375 = 0.000 0.000 + t = 1.54616461 + 1.375 t = 1.54616461 + 1.375 Combine like terms: 1.54616461 + 1.375 = 2.92116461 t = 2.92116461 Simplifying t = 2.92116461Subproblem 2
t + -1.375 = -1.54616461 Simplifying t + -1.375 = -1.54616461 Reorder the terms: -1.375 + t = -1.54616461 Solving -1.375 + t = -1.54616461 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.375' to each side of the equation. -1.375 + 1.375 + t = -1.54616461 + 1.375 Combine like terms: -1.375 + 1.375 = 0.000 0.000 + t = -1.54616461 + 1.375 t = -1.54616461 + 1.375 Combine like terms: -1.54616461 + 1.375 = -0.17116461 t = -0.17116461 Simplifying t = -0.17116461Solution
