Simplifying 0 = -4.9t2 + 14.7t + 12 Reorder the terms: 0 = 12 + 14.7t + -4.9t2 Solving 0 = 12 + 14.7t + -4.9t2 Solving for variable 't'. Combine like terms: 0 + -12 = -12 -12 + -14.7t + 4.9t2 = 12 + 14.7t + -4.9t2 + -12 + -14.7t + 4.9t2 Reorder the terms: -12 + -14.7t + 4.9t2 = 12 + -12 + 14.7t + -14.7t + -4.9t2 + 4.9t2 Combine like terms: 12 + -12 = 0 -12 + -14.7t + 4.9t2 = 0 + 14.7t + -14.7t + -4.9t2 + 4.9t2 -12 + -14.7t + 4.9t2 = 14.7t + -14.7t + -4.9t2 + 4.9t2 Combine like terms: 14.7t + -14.7t = 0.0 -12 + -14.7t + 4.9t2 = 0.0 + -4.9t2 + 4.9t2 -12 + -14.7t + 4.9t2 = -4.9t2 + 4.9t2 Combine like terms: -4.9t2 + 4.9t2 = 0.0 -12 + -14.7t + 4.9t2 = 0.0 Begin completing the square. Divide all terms by 4.9 the coefficient of the squared term: Divide each side by '4.9'. -2.448979592 + -3t + t2 = 0 Move the constant term to the right: Add '2.448979592' to each side of the equation. -2.448979592 + -3t + 2.448979592 + t2 = 0 + 2.448979592 Reorder the terms: -2.448979592 + 2.448979592 + -3t + t2 = 0 + 2.448979592 Combine like terms: -2.448979592 + 2.448979592 = 0.000000000 0.000000000 + -3t + t2 = 0 + 2.448979592 -3t + t2 = 0 + 2.448979592 Combine like terms: 0 + 2.448979592 = 2.448979592 -3t + t2 = 2.448979592 The t term is -3t. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3t + 2.25 + t2 = 2.448979592 + 2.25 Reorder the terms: 2.25 + -3t + t2 = 2.448979592 + 2.25 Combine like terms: 2.448979592 + 2.25 = 4.698979592 2.25 + -3t + t2 = 4.698979592 Factor a perfect square on the left side: (t + -1.5)(t + -1.5) = 4.698979592 Calculate the square root of the right side: 2.167712987 Break this problem into two subproblems by setting (t + -1.5) equal to 2.167712987 and -2.167712987.Subproblem 1
t + -1.5 = 2.167712987 Simplifying t + -1.5 = 2.167712987 Reorder the terms: -1.5 + t = 2.167712987 Solving -1.5 + t = 2.167712987 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + t = 2.167712987 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + t = 2.167712987 + 1.5 t = 2.167712987 + 1.5 Combine like terms: 2.167712987 + 1.5 = 3.667712987 t = 3.667712987 Simplifying t = 3.667712987Subproblem 2
