Simplifying 0 = 24t + -0.8t2 + -90 Reorder the terms: 0 = -90 + 24t + -0.8t2 Solving 0 = -90 + 24t + -0.8t2 Solving for variable 't'. Combine like terms: 0 + 90 = 90 90 + -24t + 0.8t2 = -90 + 24t + -0.8t2 + 90 + -24t + 0.8t2 Reorder the terms: 90 + -24t + 0.8t2 = -90 + 90 + 24t + -24t + -0.8t2 + 0.8t2 Combine like terms: -90 + 90 = 0 90 + -24t + 0.8t2 = 0 + 24t + -24t + -0.8t2 + 0.8t2 90 + -24t + 0.8t2 = 24t + -24t + -0.8t2 + 0.8t2 Combine like terms: 24t + -24t = 0 90 + -24t + 0.8t2 = 0 + -0.8t2 + 0.8t2 90 + -24t + 0.8t2 = -0.8t2 + 0.8t2 Combine like terms: -0.8t2 + 0.8t2 = 0.0 90 + -24t + 0.8t2 = 0.0 Begin completing the square. Divide all terms by 0.8 the coefficient of the squared term: Divide each side by '0.8'. 112.5 + -30t + t2 = 0 Move the constant term to the right: Add '-112.5' to each side of the equation. 112.5 + -30t + -112.5 + t2 = 0 + -112.5 Reorder the terms: 112.5 + -112.5 + -30t + t2 = 0 + -112.5 Combine like terms: 112.5 + -112.5 = 0.0 0.0 + -30t + t2 = 0 + -112.5 -30t + t2 = 0 + -112.5 Combine like terms: 0 + -112.5 = -112.5 -30t + t2 = -112.5 The t term is -30t. Take half its coefficient (-15). Square it (225) and add it to both sides. Add '225' to each side of the equation. -30t + 225 + t2 = -112.5 + 225 Reorder the terms: 225 + -30t + t2 = -112.5 + 225 Combine like terms: -112.5 + 225 = 112.5 225 + -30t + t2 = 112.5 Factor a perfect square on the left side: (t + -15)(t + -15) = 112.5 Calculate the square root of the right side: 10.606601718 Break this problem into two subproblems by setting (t + -15) equal to 10.606601718 and -10.606601718.Subproblem 1
t + -15 = 10.606601718 Simplifying t + -15 = 10.606601718 Reorder the terms: -15 + t = 10.606601718 Solving -15 + t = 10.606601718 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '15' to each side of the equation. -15 + 15 + t = 10.606601718 + 15 Combine like terms: -15 + 15 = 0 0 + t = 10.606601718 + 15 t = 10.606601718 + 15 Combine like terms: 10.606601718 + 15 = 25.606601718 t = 25.606601718 Simplifying t = 25.606601718Subproblem 2
