Simplifying t2 + -20t + 20 = 0 Reorder the terms: 20 + -20t + t2 = 0 Solving 20 + -20t + t2 = 0 Solving for variable 't'. Begin completing the square. Move the constant term to the right: Add '-20' to each side of the equation. 20 + -20t + -20 + t2 = 0 + -20 Reorder the terms: 20 + -20 + -20t + t2 = 0 + -20 Combine like terms: 20 + -20 = 0 0 + -20t + t2 = 0 + -20 -20t + t2 = 0 + -20 Combine like terms: 0 + -20 = -20 -20t + t2 = -20 The t term is -20t. Take half its coefficient (-10). Square it (100) and add it to both sides. Add '100' to each side of the equation. -20t + 100 + t2 = -20 + 100 Reorder the terms: 100 + -20t + t2 = -20 + 100 Combine like terms: -20 + 100 = 80 100 + -20t + t2 = 80 Factor a perfect square on the left side: (t + -10)(t + -10) = 80 Calculate the square root of the right side: 8.94427191 Break this problem into two subproblems by setting (t + -10) equal to 8.94427191 and -8.94427191.Subproblem 1
t + -10 = 8.94427191 Simplifying t + -10 = 8.94427191 Reorder the terms: -10 + t = 8.94427191 Solving -10 + t = 8.94427191 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + t = 8.94427191 + 10 Combine like terms: -10 + 10 = 0 0 + t = 8.94427191 + 10 t = 8.94427191 + 10 Combine like terms: 8.94427191 + 10 = 18.94427191 t = 18.94427191 Simplifying t = 18.94427191Subproblem 2
t + -10 = -8.94427191 Simplifying t + -10 = -8.94427191 Reorder the terms: -10 + t = -8.94427191 Solving -10 + t = -8.94427191 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + t = -8.94427191 + 10 Combine like terms: -10 + 10 = 0 0 + t = -8.94427191 + 10 t = -8.94427191 + 10 Combine like terms: -8.94427191 + 10 = 1.05572809 t = 1.05572809 Simplifying t = 1.05572809Solution
The solution to the problem is based on the solutions from the subproblems. t = {18.94427191, 1.05572809}
