Simplifying -25t2 + -20t + 4 = 0 Reorder the terms: 4 + -20t + -25t2 = 0 Solving 4 + -20t + -25t2 = 0 Solving for variable 't'. Begin completing the square. Divide all terms by -25 the coefficient of the squared term: Divide each side by '-25'. -0.16 + 0.8t + t2 = 0 Move the constant term to the right: Add '0.16' to each side of the equation. -0.16 + 0.8t + 0.16 + t2 = 0 + 0.16 Reorder the terms: -0.16 + 0.16 + 0.8t + t2 = 0 + 0.16 Combine like terms: -0.16 + 0.16 = 0.00 0.00 + 0.8t + t2 = 0 + 0.16 0.8t + t2 = 0 + 0.16 Combine like terms: 0 + 0.16 = 0.16 0.8t + t2 = 0.16 The t term is 0.8t. Take half its coefficient (0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. 0.8t + 0.16 + t2 = 0.16 + 0.16 Reorder the terms: 0.16 + 0.8t + t2 = 0.16 + 0.16 Combine like terms: 0.16 + 0.16 = 0.32 0.16 + 0.8t + t2 = 0.32 Factor a perfect square on the left side: (t + 0.4)(t + 0.4) = 0.32 Calculate the square root of the right side: 0.565685425 Break this problem into two subproblems by setting (t + 0.4) equal to 0.565685425 and -0.565685425.Subproblem 1
t + 0.4 = 0.565685425 Simplifying t + 0.4 = 0.565685425 Reorder the terms: 0.4 + t = 0.565685425 Solving 0.4 + t = 0.565685425 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + t = 0.565685425 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + t = 0.565685425 + -0.4 t = 0.565685425 + -0.4 Combine like terms: 0.565685425 + -0.4 = 0.165685425 t = 0.165685425 Simplifying t = 0.165685425Subproblem 2
t + 0.4 = -0.565685425 Simplifying t + 0.4 = -0.565685425 Reorder the terms: 0.4 + t = -0.565685425 Solving 0.4 + t = -0.565685425 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + t = -0.565685425 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + t = -0.565685425 + -0.4 t = -0.565685425 + -0.4 Combine like terms: -0.565685425 + -0.4 = -0.965685425 t = -0.965685425 Simplifying t = -0.965685425Solution
The solution to the problem is based on the solutions from the subproblems. t = {0.165685425, -0.965685425}
