Simplifying 16t2 + -32t = 212 Reorder the terms: -32t + 16t2 = 212 Solving -32t + 16t2 = 212 Solving for variable 't'. Reorder the terms: -212 + -32t + 16t2 = 212 + -212 Combine like terms: 212 + -212 = 0 -212 + -32t + 16t2 = 0 Factor out the Greatest Common Factor (GCF), '4'. 4(-53 + -8t + 4t2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(-53 + -8t + 4t2)' equal to zero and attempt to solve: Simplifying -53 + -8t + 4t2 = 0 Solving -53 + -8t + 4t2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -13.25 + -2t + t2 = 0 Move the constant term to the right: Add '13.25' to each side of the equation. -13.25 + -2t + 13.25 + t2 = 0 + 13.25 Reorder the terms: -13.25 + 13.25 + -2t + t2 = 0 + 13.25 Combine like terms: -13.25 + 13.25 = 0.00 0.00 + -2t + t2 = 0 + 13.25 -2t + t2 = 0 + 13.25 Combine like terms: 0 + 13.25 = 13.25 -2t + t2 = 13.25 The t term is -2t. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2t + 1 + t2 = 13.25 + 1 Reorder the terms: 1 + -2t + t2 = 13.25 + 1 Combine like terms: 13.25 + 1 = 14.25 1 + -2t + t2 = 14.25 Factor a perfect square on the left side: (t + -1)(t + -1) = 14.25 Calculate the square root of the right side: 3.774917218 Break this problem into two subproblems by setting (t + -1) equal to 3.774917218 and -3.774917218.Subproblem 1
t + -1 = 3.774917218 Simplifying t + -1 = 3.774917218 Reorder the terms: -1 + t = 3.774917218 Solving -1 + t = 3.774917218 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + t = 3.774917218 + 1 Combine like terms: -1 + 1 = 0 0 + t = 3.774917218 + 1 t = 3.774917218 + 1 Combine like terms: 3.774917218 + 1 = 4.774917218 t = 4.774917218 Simplifying t = 4.774917218Subproblem 2
t + -1 = -3.774917218 Simplifying t + -1 = -3.774917218 Reorder the terms: -1 + t = -3.774917218 Solving -1 + t = -3.774917218 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + t = -3.774917218 + 1 Combine like terms: -1 + 1 = 0 0 + t = -3.774917218 + 1 t = -3.774917218 + 1 Combine like terms: -3.774917218 + 1 = -2.774917218 t = -2.774917218 Simplifying t = -2.774917218Solution
