Simplifying -16t2 + -10t + 110 = 0 Reorder the terms: 110 + -10t + -16t2 = 0 Solving 110 + -10t + -16t2 = 0 Solving for variable 't'. Factor out the Greatest Common Factor (GCF), '2'. 2(55 + -5t + -8t2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(55 + -5t + -8t2)' equal to zero and attempt to solve: Simplifying 55 + -5t + -8t2 = 0 Solving 55 + -5t + -8t2 = 0 Begin completing the square. Divide all terms by -8 the coefficient of the squared term: Divide each side by '-8'. -6.875 + 0.625t + t2 = 0 Move the constant term to the right: Add '6.875' to each side of the equation. -6.875 + 0.625t + 6.875 + t2 = 0 + 6.875 Reorder the terms: -6.875 + 6.875 + 0.625t + t2 = 0 + 6.875 Combine like terms: -6.875 + 6.875 = 0.000 0.000 + 0.625t + t2 = 0 + 6.875 0.625t + t2 = 0 + 6.875 Combine like terms: 0 + 6.875 = 6.875 0.625t + t2 = 6.875 The t term is 0.625t. Take half its coefficient (0.3125). Square it (0.09765625) and add it to both sides. Add '0.09765625' to each side of the equation. 0.625t + 0.09765625 + t2 = 6.875 + 0.09765625 Reorder the terms: 0.09765625 + 0.625t + t2 = 6.875 + 0.09765625 Combine like terms: 6.875 + 0.09765625 = 6.97265625 0.09765625 + 0.625t + t2 = 6.97265625 Factor a perfect square on the left side: (t + 0.3125)(t + 0.3125) = 6.97265625 Calculate the square root of the right side: 2.640578772 Break this problem into two subproblems by setting (t + 0.3125) equal to 2.640578772 and -2.640578772.Subproblem 1
t + 0.3125 = 2.640578772 Simplifying t + 0.3125 = 2.640578772 Reorder the terms: 0.3125 + t = 2.640578772 Solving 0.3125 + t = 2.640578772 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.3125' to each side of the equation. 0.3125 + -0.3125 + t = 2.640578772 + -0.3125 Combine like terms: 0.3125 + -0.3125 = 0.0000 0.0000 + t = 2.640578772 + -0.3125 t = 2.640578772 + -0.3125 Combine like terms: 2.640578772 + -0.3125 = 2.328078772 t = 2.328078772 Simplifying t = 2.328078772Subproblem 2
t + 0.3125 = -2.640578772 Simplifying t + 0.3125 = -2.640578772 Reorder the terms: 0.3125 + t = -2.640578772 Solving 0.3125 + t = -2.640578772 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.3125' to each side of the equation. 0.3125 + -0.3125 + t = -2.640578772 + -0.3125 Combine like terms: 0.3125 + -0.3125 = 0.0000 0.0000 + t = -2.640578772 + -0.3125 t = -2.640578772 + -0.3125 Combine like terms: -2.640578772 + -0.3125 = -2.953078772 t = -2.953078772 Simplifying t = -2.953078772Solution
The solution to the problem is based on the solutions from the subproblems. t = {2.328078772, -2.953078772}Solution
t = {2.328078772, -2.953078772}
