Simplifying 0 = 16t2 + 80t + 10 Reorder the terms: 0 = 10 + 80t + 16t2 Solving 0 = 10 + 80t + 16t2 Solving for variable 't'. Combine like terms: 0 + -10 = -10 -10 + -80t + -16t2 = 10 + 80t + 16t2 + -10 + -80t + -16t2 Reorder the terms: -10 + -80t + -16t2 = 10 + -10 + 80t + -80t + 16t2 + -16t2 Combine like terms: 10 + -10 = 0 -10 + -80t + -16t2 = 0 + 80t + -80t + 16t2 + -16t2 -10 + -80t + -16t2 = 80t + -80t + 16t2 + -16t2 Combine like terms: 80t + -80t = 0 -10 + -80t + -16t2 = 0 + 16t2 + -16t2 -10 + -80t + -16t2 = 16t2 + -16t2 Combine like terms: 16t2 + -16t2 = 0 -10 + -80t + -16t2 = 0 Factor out the Greatest Common Factor (GCF), '-2'. -2(5 + 40t + 8t2) = 0 Ignore the factor -2.Subproblem 1
Set the factor '(5 + 40t + 8t2)' equal to zero and attempt to solve: Simplifying 5 + 40t + 8t2 = 0 Solving 5 + 40t + 8t2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.625 + 5t + t2 = 0 Move the constant term to the right: Add '-0.625' to each side of the equation. 0.625 + 5t + -0.625 + t2 = 0 + -0.625 Reorder the terms: 0.625 + -0.625 + 5t + t2 = 0 + -0.625 Combine like terms: 0.625 + -0.625 = 0.000 0.000 + 5t + t2 = 0 + -0.625 5t + t2 = 0 + -0.625 Combine like terms: 0 + -0.625 = -0.625 5t + t2 = -0.625 The t term is 5t. Take half its coefficient (2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. 5t + 6.25 + t2 = -0.625 + 6.25 Reorder the terms: 6.25 + 5t + t2 = -0.625 + 6.25 Combine like terms: -0.625 + 6.25 = 5.625 6.25 + 5t + t2 = 5.625 Factor a perfect square on the left side: (t + 2.5)(t + 2.5) = 5.625 Calculate the square root of the right side: 2.371708245 Break this problem into two subproblems by setting (t + 2.5) equal to 2.371708245 and -2.371708245.Subproblem 1
t + 2.5 = 2.371708245 Simplifying t + 2.5 = 2.371708245 Reorder the terms: 2.5 + t = 2.371708245 Solving 2.5 + t = 2.371708245 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + t = 2.371708245 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + t = 2.371708245 + -2.5 t = 2.371708245 + -2.5 Combine like terms: 2.371708245 + -2.5 = -0.128291755 t = -0.128291755 Simplifying t = -0.128291755Subproblem 2
t + 2.5 = -2.371708245 Simplifying t + 2.5 = -2.371708245 Reorder the terms: 2.5 + t = -2.371708245 Solving 2.5 + t = -2.371708245 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + t = -2.371708245 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + t = -2.371708245 + -2.5 t = -2.371708245 + -2.5 Combine like terms: -2.371708245 + -2.5 = -4.871708245 t = -4.871708245 Simplifying t = -4.871708245Solution
