Simplifying 440 = -16t2 + -7t + 470 Reorder the terms: 440 = 470 + -7t + -16t2 Solving 440 = 470 + -7t + -16t2 Solving for variable 't'. Combine like terms: 440 + -470 = -30 -30 + 7t + 16t2 = 470 + -7t + -16t2 + -470 + 7t + 16t2 Reorder the terms: -30 + 7t + 16t2 = 470 + -470 + -7t + 7t + -16t2 + 16t2 Combine like terms: 470 + -470 = 0 -30 + 7t + 16t2 = 0 + -7t + 7t + -16t2 + 16t2 -30 + 7t + 16t2 = -7t + 7t + -16t2 + 16t2 Combine like terms: -7t + 7t = 0 -30 + 7t + 16t2 = 0 + -16t2 + 16t2 -30 + 7t + 16t2 = -16t2 + 16t2 Combine like terms: -16t2 + 16t2 = 0 -30 + 7t + 16t2 = 0 Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. -1.875 + 0.4375t + t2 = 0 Move the constant term to the right: Add '1.875' to each side of the equation. -1.875 + 0.4375t + 1.875 + t2 = 0 + 1.875 Reorder the terms: -1.875 + 1.875 + 0.4375t + t2 = 0 + 1.875 Combine like terms: -1.875 + 1.875 = 0.000 0.000 + 0.4375t + t2 = 0 + 1.875 0.4375t + t2 = 0 + 1.875 Combine like terms: 0 + 1.875 = 1.875 0.4375t + t2 = 1.875 The t term is 0.4375t. Take half its coefficient (0.21875). Square it (0.0478515625) and add it to both sides. Add '0.0478515625' to each side of the equation. 0.4375t + 0.0478515625 + t2 = 1.875 + 0.0478515625 Reorder the terms: 0.0478515625 + 0.4375t + t2 = 1.875 + 0.0478515625 Combine like terms: 1.875 + 0.0478515625 = 1.9228515625 0.0478515625 + 0.4375t + t2 = 1.9228515625 Factor a perfect square on the left side: (t + 0.21875)(t + 0.21875) = 1.9228515625 Calculate the square root of the right side: 1.386669233 Break this problem into two subproblems by setting (t + 0.21875) equal to 1.386669233 and -1.386669233.Subproblem 1
t + 0.21875 = 1.386669233 Simplifying t + 0.21875 = 1.386669233 Reorder the terms: 0.21875 + t = 1.386669233 Solving 0.21875 + t = 1.386669233 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.21875' to each side of the equation. 0.21875 + -0.21875 + t = 1.386669233 + -0.21875 Combine like terms: 0.21875 + -0.21875 = 0.00000 0.00000 + t = 1.386669233 + -0.21875 t = 1.386669233 + -0.21875 Combine like terms: 1.386669233 + -0.21875 = 1.167919233 t = 1.167919233 Simplifying t = 1.167919233Subproblem 2
t + 0.21875 = -1.386669233 Simplifying t + 0.21875 = -1.386669233 Reorder the terms: 0.21875 + t = -1.386669233 Solving 0.21875 + t = -1.386669233 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right.
