Simplifying 2 + 5t + -5t2 = 0 Solving 2 + 5t + -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'. -0.4 + -1t + t2 = 0 Move the constant term to the right: Add '0.4' to each side of the equation. -0.4 + -1t + 0.4 + t2 = 0 + 0.4 Reorder the terms: -0.4 + 0.4 + -1t + t2 = 0 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + -1t + t2 = 0 + 0.4 -1t + t2 = 0 + 0.4 Combine like terms: 0 + 0.4 = 0.4 -1t + t2 = 0.4 The t term is -1t. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1t + 0.25 + t2 = 0.4 + 0.25 Reorder the terms: 0.25 + -1t + t2 = 0.4 + 0.25 Combine like terms: 0.4 + 0.25 = 0.65 0.25 + -1t + t2 = 0.65 Factor a perfect square on the left side: (t + -0.5)(t + -0.5) = 0.65 Calculate the square root of the right side: 0.806225775 Break this problem into two subproblems by setting (t + -0.5) equal to 0.806225775 and -0.806225775.Subproblem 1
t + -0.5 = 0.806225775 Simplifying t + -0.5 = 0.806225775 Reorder the terms: -0.5 + t = 0.806225775 Solving -0.5 + t = 0.806225775 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + t = 0.806225775 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + t = 0.806225775 + 0.5 t = 0.806225775 + 0.5 Combine like terms: 0.806225775 + 0.5 = 1.306225775 t = 1.306225775 Simplifying t = 1.306225775Subproblem 2
t + -0.5 = -0.806225775 Simplifying t + -0.5 = -0.806225775 Reorder the terms: -0.5 + t = -0.806225775 Solving -0.5 + t = -0.806225775 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + t = -0.806225775 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + t = -0.806225775 + 0.5 t = -0.806225775 + 0.5 Combine like terms: -0.806225775 + 0.5 = -0.306225775 t = -0.306225775 Simplifying t = -0.306225775Solution
The solution to the problem is based on the solutions from the subproblems. t = {1.306225775, -0.306225775}
