Simplifying t2 + 15t + -6 = 0 Reorder the terms: -6 + 15t + t2 = 0 Solving -6 + 15t + t2 = 0 Solving for variable 't'. Begin completing the square. Move the constant term to the right: Add '6' to each side of the equation. -6 + 15t + 6 + t2 = 0 + 6 Reorder the terms: -6 + 6 + 15t + t2 = 0 + 6 Combine like terms: -6 + 6 = 0 0 + 15t + t2 = 0 + 6 15t + t2 = 0 + 6 Combine like terms: 0 + 6 = 6 15t + t2 = 6 The t term is 15t. Take half its coefficient (7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. 15t + 56.25 + t2 = 6 + 56.25 Reorder the terms: 56.25 + 15t + t2 = 6 + 56.25 Combine like terms: 6 + 56.25 = 62.25 56.25 + 15t + t2 = 62.25 Factor a perfect square on the left side: (t + 7.5)(t + 7.5) = 62.25 Calculate the square root of the right side: 7.889866919 Break this problem into two subproblems by setting (t + 7.5) equal to 7.889866919 and -7.889866919.Subproblem 1
t + 7.5 = 7.889866919 Simplifying t + 7.5 = 7.889866919 Reorder the terms: 7.5 + t = 7.889866919 Solving 7.5 + t = 7.889866919 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + t = 7.889866919 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + t = 7.889866919 + -7.5 t = 7.889866919 + -7.5 Combine like terms: 7.889866919 + -7.5 = 0.389866919 t = 0.389866919 Simplifying t = 0.389866919Subproblem 2
t + 7.5 = -7.889866919 Simplifying t + 7.5 = -7.889866919 Reorder the terms: 7.5 + t = -7.889866919 Solving 7.5 + t = -7.889866919 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + t = -7.889866919 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + t = -7.889866919 + -7.5 t = -7.889866919 + -7.5 Combine like terms: -7.889866919 + -7.5 = -15.389866919 t = -15.389866919 Simplifying t = -15.389866919Solution
The solution to the problem is based on the solutions from the subproblems. t = {0.389866919, -15.389866919}
