Simplifying 25t2 + -40t = 16 Reorder the terms: -40t + 25t2 = 16 Solving -40t + 25t2 = 16 Solving for variable 't'. Reorder the terms: -16 + -40t + 25t2 = 16 + -16 Combine like terms: 16 + -16 = 0 -16 + -40t + 25t2 = 0 Begin completing the square. Divide all terms by 25 the coefficient of the squared term: Divide each side by '25'. -0.64 + -1.6t + t2 = 0 Move the constant term to the right: Add '0.64' to each side of the equation. -0.64 + -1.6t + 0.64 + t2 = 0 + 0.64 Reorder the terms: -0.64 + 0.64 + -1.6t + t2 = 0 + 0.64 Combine like terms: -0.64 + 0.64 = 0.00 0.00 + -1.6t + t2 = 0 + 0.64 -1.6t + t2 = 0 + 0.64 Combine like terms: 0 + 0.64 = 0.64 -1.6t + t2 = 0.64 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 = 0.64 + 0.64 Reorder the terms: 0.64 + -1.6t + t2 = 0.64 + 0.64 Combine like terms: 0.64 + 0.64 = 1.28 0.64 + -1.6t + t2 = 1.28 Factor a perfect square on the left side: (t + -0.8)(t + -0.8) = 1.28 Calculate the square root of the right side: 1.13137085 Break this problem into two subproblems by setting (t + -0.8) equal to 1.13137085 and -1.13137085.Subproblem 1
t + -0.8 = 1.13137085 Simplifying t + -0.8 = 1.13137085 Reorder the terms: -0.8 + t = 1.13137085 Solving -0.8 + t = 1.13137085 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 = 1.13137085 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + t = 1.13137085 + 0.8 t = 1.13137085 + 0.8 Combine like terms: 1.13137085 + 0.8 = 1.93137085 t = 1.93137085 Simplifying t = 1.93137085Subproblem 2
t + -0.8 = -1.13137085 Simplifying t + -0.8 = -1.13137085 Reorder the terms: -0.8 + t = -1.13137085 Solving -0.8 + t = -1.13137085 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 = -1.13137085 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + t = -1.13137085 + 0.8 t = -1.13137085 + 0.8 Combine like terms: -1.13137085 + 0.8 = -0.33137085 t = -0.33137085 Simplifying t = -0.33137085Solution
The solution to the problem is based on the solutions from the subproblems. t = {1.93137085, -0.33137085}
