Simplifying 5t2 + 0.39t + -0.9 = 0 Reorder the terms: -0.9 + 0.39t + 5t2 = 0 Solving -0.9 + 0.39t + 5t2 = 0 Solving for variable 't'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -0.18 + 0.078t + t2 = 0 Move the constant term to the right: Add '0.18' to each side of the equation. -0.18 + 0.078t + 0.18 + t2 = 0 + 0.18 Reorder the terms: -0.18 + 0.18 + 0.078t + t2 = 0 + 0.18 Combine like terms: -0.18 + 0.18 = 0.00 0.00 + 0.078t + t2 = 0 + 0.18 0.078t + t2 = 0 + 0.18 Combine like terms: 0 + 0.18 = 0.18 0.078t + t2 = 0.18 The t term is 0.078t. Take half its coefficient (0.039). Square it (0.001521) and add it to both sides. Add '0.001521' to each side of the equation. 0.078t + 0.001521 + t2 = 0.18 + 0.001521 Reorder the terms: 0.001521 + 0.078t + t2 = 0.18 + 0.001521 Combine like terms: 0.18 + 0.001521 = 0.181521 0.001521 + 0.078t + t2 = 0.181521 Factor a perfect square on the left side: (t + 0.039)(t + 0.039) = 0.181521 Calculate the square root of the right side: 0.426052814 Break this problem into two subproblems by setting (t + 0.039) equal to 0.426052814 and -0.426052814.Subproblem 1
t + 0.039 = 0.426052814 Simplifying t + 0.039 = 0.426052814 Reorder the terms: 0.039 + t = 0.426052814 Solving 0.039 + t = 0.426052814 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.039' to each side of the equation. 0.039 + -0.039 + t = 0.426052814 + -0.039 Combine like terms: 0.039 + -0.039 = 0.000 0.000 + t = 0.426052814 + -0.039 t = 0.426052814 + -0.039 Combine like terms: 0.426052814 + -0.039 = 0.387052814 t = 0.387052814 Simplifying t = 0.387052814Subproblem 2
t + 0.039 = -0.426052814 Simplifying t + 0.039 = -0.426052814 Reorder the terms: 0.039 + t = -0.426052814 Solving 0.039 + t = -0.426052814 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.039' to each side of the equation. 0.039 + -0.039 + t = -0.426052814 + -0.039 Combine like terms: 0.039 + -0.039 = 0.000 0.000 + t = -0.426052814 + -0.039 t = -0.426052814 + -0.039 Combine like terms: -0.426052814 + -0.039 = -0.465052814 t = -0.465052814 Simplifying t = -0.465052814Solution
The solution to the problem is based on the solutions from the subproblems. t = {0.387052814, -0.465052814}
