Simplifying -0.2t2 + 1.6t + 0.64 = -0.64 Reorder the terms: 0.64 + 1.6t + -0.2t2 = -0.64 Solving 0.64 + 1.6t + -0.2t2 = -0.64 Solving for variable 't'. Reorder the terms: 0.64 + 0.64 + 1.6t + -0.2t2 = -0.64 + 0.64 Combine like terms: 0.64 + 0.64 = 1.28 1.28 + 1.6t + -0.2t2 = -0.64 + 0.64 Combine like terms: -0.64 + 0.64 = 0.00 1.28 + 1.6t + -0.2t2 = 0.00 Begin completing the square. Divide all terms by -0.2 the coefficient of the squared term: Divide each side by '-0.2'. -6.4 + -8t + t2 = 0.0 Move the constant term to the right: Add '6.4' to each side of the equation. -6.4 + -8t + 6.4 + t2 = 0.0 + 6.4 Reorder the terms: -6.4 + 6.4 + -8t + t2 = 0.0 + 6.4 Combine like terms: -6.4 + 6.4 = 0.0 0.0 + -8t + t2 = 0.0 + 6.4 -8t + t2 = 0.0 + 6.4 Combine like terms: 0.0 + 6.4 = 6.4 -8t + t2 = 6.4 The t term is -8t. Take half its coefficient (-4). Square it (16) and add it to both sides. Add '16' to each side of the equation. -8t + 16 + t2 = 6.4 + 16 Reorder the terms: 16 + -8t + t2 = 6.4 + 16 Combine like terms: 6.4 + 16 = 22.4 16 + -8t + t2 = 22.4 Factor a perfect square on the left side: (t + -4)(t + -4) = 22.4 Calculate the square root of the right side: 4.732863826 Break this problem into two subproblems by setting (t + -4) equal to 4.732863826 and -4.732863826.Subproblem 1
t + -4 = 4.732863826 Simplifying t + -4 = 4.732863826 Reorder the terms: -4 + t = 4.732863826 Solving -4 + t = 4.732863826 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + t = 4.732863826 + 4 Combine like terms: -4 + 4 = 0 0 + t = 4.732863826 + 4 t = 4.732863826 + 4 Combine like terms: 4.732863826 + 4 = 8.732863826 t = 8.732863826 Simplifying t = 8.732863826Subproblem 2
t + -4 = -4.732863826 Simplifying t + -4 = -4.732863826 Reorder the terms: -4 + t = -4.732863826 Solving -4 + t = -4.732863826 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + t = -4.732863826 + 4 Combine like terms: -4 + 4 = 0 0 + t = -4.732863826 + 4 t = -4.732863826 + 4 Combine like terms: -4.732863826 + 4 = -0.732863826 t = -0.732863826 Simplifying t = -0.732863826Solution
