Simplifying -16t2 + 16t + 35 = 0 Reorder the terms: 35 + 16t + -16t2 = 0 Solving 35 + 16t + -16t2 = 0 Solving for variable 't'. Begin completing the square. Divide all terms by -16 the coefficient of the squared term: Divide each side by '-16'. -2.1875 + -1t + t2 = 0 Move the constant term to the right: Add '2.1875' to each side of the equation. -2.1875 + -1t + 2.1875 + t2 = 0 + 2.1875 Reorder the terms: -2.1875 + 2.1875 + -1t + t2 = 0 + 2.1875 Combine like terms: -2.1875 + 2.1875 = 0.0000 0.0000 + -1t + t2 = 0 + 2.1875 -1t + t2 = 0 + 2.1875 Combine like terms: 0 + 2.1875 = 2.1875 -1t + t2 = 2.1875 The t term is -1t. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1t + 0.25 + t2 = 2.1875 + 0.25 Reorder the terms: 0.25 + -1t + t2 = 2.1875 + 0.25 Combine like terms: 2.1875 + 0.25 = 2.4375 0.25 + -1t + t2 = 2.4375 Factor a perfect square on the left side: (t + -0.5)(t + -0.5) = 2.4375 Calculate the square root of the right side: 1.5612495 Break this problem into two subproblems by setting (t + -0.5) equal to 1.5612495 and -1.5612495.Subproblem 1
t + -0.5 = 1.5612495 Simplifying t + -0.5 = 1.5612495 Reorder the terms: -0.5 + t = 1.5612495 Solving -0.5 + t = 1.5612495 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + t = 1.5612495 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + t = 1.5612495 + 0.5 t = 1.5612495 + 0.5 Combine like terms: 1.5612495 + 0.5 = 2.0612495 t = 2.0612495 Simplifying t = 2.0612495Subproblem 2
t + -0.5 = -1.5612495 Simplifying t + -0.5 = -1.5612495 Reorder the terms: -0.5 + t = -1.5612495 Solving -0.5 + t = -1.5612495 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + t = -1.5612495 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + t = -1.5612495 + 0.5 t = -1.5612495 + 0.5 Combine like terms: -1.5612495 + 0.5 = -1.0612495 t = -1.0612495 Simplifying t = -1.0612495Solution
