Set the factor '(-47 + -25t + 8t2)' equal to zero and attempt to solve: Simplifying -47 + -25t + 8t2 = 0 Solving -47 + -25t + 8t2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -5.875 + -3.125t + t2 = 0 Move the constant term to the right: Add '5.875' to each side of the equation. -5.875 + -3.125t + 5.875 + t2 = 0 + 5.875 Reorder the terms: -5.875 + 5.875 + -3.125t + t2 = 0 + 5.875 Combine like terms: -5.875 + 5.875 = 0.000 0.000 + -3.125t + t2 = 0 + 5.875 -3.125t + t2 = 0 + 5.875 Combine like terms: 0 + 5.875 = 5.875 -3.125t + t2 = 5.875 The t term is -3.125t. Take half its coefficient (-1.5625). Square it (2.44140625) and add it to both sides. Add '2.44140625' to each side of the equation. -3.125t + 2.44140625 + t2 = 5.875 + 2.44140625 Reorder the terms: 2.44140625 + -3.125t + t2 = 5.875 + 2.44140625 Combine like terms: 5.875 + 2.44140625 = 8.31640625 2.44140625 + -3.125t + t2 = 8.31640625 Factor a perfect square on the left side: (t + -1.5625)(t + -1.5625) = 8.31640625 Calculate the square root of the right side: 2.883817999 Break this problem into two subproblems by setting (t + -1.5625) equal to 2.883817999 and -2.883817999.Subproblem 1
t + -1.5625 = 2.883817999 Simplifying t + -1.5625 = 2.883817999 Reorder the terms: -1.5625 + t = 2.883817999 Solving -1.5625 + t = 2.883817999 Solving for variable 't'.
