Simplifying 2t2 + -5t + -9 = 0 Reorder the terms: -9 + -5t + 2t2 = 0 Solving -9 + -5t + 2t2 = 0 Solving for variable 't'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -4.5 + -2.5t + t2 = 0 Move the constant term to the right: Add '4.5' to each side of the equation. -4.5 + -2.5t + 4.5 + t2 = 0 + 4.5 Reorder the terms: -4.5 + 4.5 + -2.5t + t2 = 0 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + -2.5t + t2 = 0 + 4.5 -2.5t + t2 = 0 + 4.5 Combine like terms: 0 + 4.5 = 4.5 -2.5t + t2 = 4.5 The t term is -2.5t. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5t + 1.5625 + t2 = 4.5 + 1.5625 Reorder the terms: 1.5625 + -2.5t + t2 = 4.5 + 1.5625 Combine like terms: 4.5 + 1.5625 = 6.0625 1.5625 + -2.5t + t2 = 6.0625 Factor a perfect square on the left side: (t + -1.25)(t + -1.25) = 6.0625 Calculate the square root of the right side: 2.46221445 Break this problem into two subproblems by setting (t + -1.25) equal to 2.46221445 and -2.46221445.Subproblem 1
t + -1.25 = 2.46221445 Simplifying t + -1.25 = 2.46221445 Reorder the terms: -1.25 + t = 2.46221445 Solving -1.25 + t = 2.46221445 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + t = 2.46221445 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + t = 2.46221445 + 1.25 t = 2.46221445 + 1.25 Combine like terms: 2.46221445 + 1.25 = 3.71221445 t = 3.71221445 Simplifying t = 3.71221445Subproblem 2
t + -1.25 = -2.46221445 Simplifying t + -1.25 = -2.46221445 Reorder the terms: -1.25 + t = -2.46221445 Solving -1.25 + t = -2.46221445 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + t = -2.46221445 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + t = -2.46221445 + 1.25 t = -2.46221445 + 1.25 Combine like terms: -2.46221445 + 1.25 = -1.21221445 t = -1.21221445 Simplifying t = -1.21221445Solution
The solution to the problem is based on the solutions from the subproblems. t = {3.71221445, -1.21221445}
