Simplifying 2 = 8t + -5t2 Solving 2 = 8t + -5t2 Solving for variable 't'. Reorder the terms: 2 + -8t + 5t2 = 8t + -8t + -5t2 + 5t2 Combine like terms: 8t + -8t = 0 2 + -8t + 5t2 = 0 + -5t2 + 5t2 2 + -8t + 5t2 = -5t2 + 5t2 Combine like terms: -5t2 + 5t2 = 0 2 + -8t + 5t2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 0.4 + -1.6t + t2 = 0 Move the constant term to the right: Add '-0.4' to each side of the equation. 0.4 + -1.6t + -0.4 + t2 = 0 + -0.4 Reorder the terms: 0.4 + -0.4 + -1.6t + t2 = 0 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + -1.6t + t2 = 0 + -0.4 -1.6t + t2 = 0 + -0.4 Combine like terms: 0 + -0.4 = -0.4 -1.6t + t2 = -0.4 The t term is -1.6t. Take half its coefficient (-0.8). Square it (0.64) and add it to both sides. Add '0.64' to each side of the equation. -1.6t + 0.64 + t2 = -0.4 + 0.64 Reorder the terms: 0.64 + -1.6t + t2 = -0.4 + 0.64 Combine like terms: -0.4 + 0.64 = 0.24 0.64 + -1.6t + t2 = 0.24 Factor a perfect square on the left side: (t + -0.8)(t + -0.8) = 0.24 Calculate the square root of the right side: 0.489897949 Break this problem into two subproblems by setting (t + -0.8) equal to 0.489897949 and -0.489897949.Subproblem 1
t + -0.8 = 0.489897949 Simplifying t + -0.8 = 0.489897949 Reorder the terms: -0.8 + t = 0.489897949 Solving -0.8 + t = 0.489897949 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + t = 0.489897949 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + t = 0.489897949 + 0.8 t = 0.489897949 + 0.8 Combine like terms: 0.489897949 + 0.8 = 1.289897949 t = 1.289897949 Simplifying t = 1.289897949Subproblem 2
t + -0.8 = -0.489897949 Simplifying t + -0.8 = -0.489897949 Reorder the terms: -0.8 + t = -0.489897949 Solving -0.8 + t = -0.489897949 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + t = -0.489897949 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + t = -0.489897949 + 0.8 t = -0.489897949 + 0.8 Combine like terms: -0.489897949 + 0.8 = 0.310102051 t = 0.310102051 Simplifying t = 0.310102051Solution
The solution to the problem is based on the solutions from the subproblems. t = {1.289897949, 0.310102051}
