Simplifying t2 + 8t + -72 = 0 Reorder the terms: -72 + 8t + t2 = 0 Solving -72 + 8t + t2 = 0 Solving for variable 't'. Begin completing the square. Move the constant term to the right: Add '72' to each side of the equation. -72 + 8t + 72 + t2 = 0 + 72 Reorder the terms: -72 + 72 + 8t + t2 = 0 + 72 Combine like terms: -72 + 72 = 0 0 + 8t + t2 = 0 + 72 8t + t2 = 0 + 72 Combine like terms: 0 + 72 = 72 8t + t2 = 72 The t term is 8t. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8t + 16 + t2 = 72 + 16 Reorder the terms: 16 + 8t + t2 = 72 + 16 Combine like terms: 72 + 16 = 88 16 + 8t + t2 = 88 Factor a perfect square on the left side: (t + 4)(t + 4) = 88 Calculate the square root of the right side: 9.38083152 Break this problem into two subproblems by setting (t + 4) equal to 9.38083152 and -9.38083152.Subproblem 1
t + 4 = 9.38083152 Simplifying t + 4 = 9.38083152 Reorder the terms: 4 + t = 9.38083152 Solving 4 + t = 9.38083152 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + t = 9.38083152 + -4 Combine like terms: 4 + -4 = 0 0 + t = 9.38083152 + -4 t = 9.38083152 + -4 Combine like terms: 9.38083152 + -4 = 5.38083152 t = 5.38083152 Simplifying t = 5.38083152Subproblem 2
t + 4 = -9.38083152 Simplifying t + 4 = -9.38083152 Reorder the terms: 4 + t = -9.38083152 Solving 4 + t = -9.38083152 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + t = -9.38083152 + -4 Combine like terms: 4 + -4 = 0 0 + t = -9.38083152 + -4 t = -9.38083152 + -4 Combine like terms: -9.38083152 + -4 = -13.38083152 t = -13.38083152 Simplifying t = -13.38083152Solution
The solution to the problem is based on the solutions from the subproblems. t = {5.38083152, -13.38083152}
