Simplifying 0 = -16t2 + 10t + 10 Reorder the terms: 0 = 10 + 10t + -16t2 Solving 0 = 10 + 10t + -16t2 Solving for variable 't'. Combine like terms: 0 + -10 = -10 -10 + -10t + 16t2 = 10 + 10t + -16t2 + -10 + -10t + 16t2 Reorder the terms: -10 + -10t + 16t2 = 10 + -10 + 10t + -10t + -16t2 + 16t2 Combine like terms: 10 + -10 = 0 -10 + -10t + 16t2 = 0 + 10t + -10t + -16t2 + 16t2 -10 + -10t + 16t2 = 10t + -10t + -16t2 + 16t2 Combine like terms: 10t + -10t = 0 -10 + -10t + 16t2 = 0 + -16t2 + 16t2 -10 + -10t + 16t2 = -16t2 + 16t2 Combine like terms: -16t2 + 16t2 = 0 -10 + -10t + 16t2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-5 + -5t + 8t2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-5 + -5t + 8t2)' equal to zero and attempt to solve: Simplifying -5 + -5t + 8t2 = 0 Solving -5 + -5t + 8t2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -0.625 + -0.625t + t2 = 0 Move the constant term to the right: Add '0.625' to each side of the equation. -0.625 + -0.625t + 0.625 + t2 = 0 + 0.625 Reorder the terms: -0.625 + 0.625 + -0.625t + t2 = 0 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + -0.625t + t2 = 0 + 0.625 -0.625t + t2 = 0 + 0.625 Combine like terms: 0 + 0.625 = 0.625 -0.625t + t2 = 0.625 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 = 0.625 + 0.09765625 Reorder the terms: 0.09765625 + -0.625t + t2 = 0.625 + 0.09765625 Combine like terms: 0.625 + 0.09765625 = 0.72265625 0.09765625 + -0.625t + t2 = 0.72265625 Factor a perfect square on the left side: (t + -0.3125)(t + -0.3125) = 0.72265625 Calculate the square root of the right side: 0.850091907 Break this problem into two subproblems by setting (t + -0.3125) equal to 0.850091907 and -0.850091907.Subproblem 1
t + -0.3125 = 0.850091907 Simplifying t + -0.3125 = 0.850091907 Reorder the terms: -0.3125 + t = 0.850091907 Solving -0.3125 + t = 0.850091907 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 = 0.850091907 + 0.3125 Combine like terms: -0.3125 + 0.3125 = 0.0000 0.0000 + t = 0.850091907 + 0.3125 t = 0.850091907 + 0.3125 Combine like terms: 0.850091907 + 0.3125 = 1.162591907 t = 1.162591907 Simplifying t = 1.162591907Subproblem 2
t + -0.3125 = -0.850091907 Simplifying t + -0.3125 = -0.850091907 Reorder the terms: -0.3125 + t = -0.850091907 Solving -0.3125 + t = -0.850091907 Solving for variable 't'.
