Simplifying 16t2 + -32t + 5 = 0 Reorder the terms: 5 + -32t + 16t2 = 0 Solving 5 + -32t + 16t2 = 0 Solving for variable 't'. Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. 0.3125 + -2t + t2 = 0 Move the constant term to the right: Add '-0.3125' to each side of the equation. 0.3125 + -2t + -0.3125 + t2 = 0 + -0.3125 Reorder the terms: 0.3125 + -0.3125 + -2t + t2 = 0 + -0.3125 Combine like terms: 0.3125 + -0.3125 = 0.0000 0.0000 + -2t + t2 = 0 + -0.3125 -2t + t2 = 0 + -0.3125 Combine like terms: 0 + -0.3125 = -0.3125 -2t + t2 = -0.3125 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 = -0.3125 + 1 Reorder the terms: 1 + -2t + t2 = -0.3125 + 1 Combine like terms: -0.3125 + 1 = 0.6875 1 + -2t + t2 = 0.6875 Factor a perfect square on the left side: (t + -1)(t + -1) = 0.6875 Calculate the square root of the right side: 0.829156198 Break this problem into two subproblems by setting (t + -1) equal to 0.829156198 and -0.829156198.Subproblem 1
t + -1 = 0.829156198 Simplifying t + -1 = 0.829156198 Reorder the terms: -1 + t = 0.829156198 Solving -1 + t = 0.829156198 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 = 0.829156198 + 1 Combine like terms: -1 + 1 = 0 0 + t = 0.829156198 + 1 t = 0.829156198 + 1 Combine like terms: 0.829156198 + 1 = 1.829156198 t = 1.829156198 Simplifying t = 1.829156198Subproblem 2
t + -1 = -0.829156198 Simplifying t + -1 = -0.829156198 Reorder the terms: -1 + t = -0.829156198 Solving -1 + t = -0.829156198 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 = -0.829156198 + 1 Combine like terms: -1 + 1 = 0 0 + t = -0.829156198 + 1 t = -0.829156198 + 1 Combine like terms: -0.829156198 + 1 = 0.170843802 t = 0.170843802 Simplifying t = 0.170843802Solution
