Simplifying 4t2 + -3t + -25 = 0 Reorder the terms: -25 + -3t + 4t2 = 0 Solving -25 + -3t + 4t2 = 0 Solving for variable 't'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -6.25 + -0.75t + t2 = 0 Move the constant term to the right: Add '6.25' to each side of the equation. -6.25 + -0.75t + 6.25 + t2 = 0 + 6.25 Reorder the terms: -6.25 + 6.25 + -0.75t + t2 = 0 + 6.25 Combine like terms: -6.25 + 6.25 = 0.00 0.00 + -0.75t + t2 = 0 + 6.25 -0.75t + t2 = 0 + 6.25 Combine like terms: 0 + 6.25 = 6.25 -0.75t + t2 = 6.25 The t term is -0.75t. Take half its coefficient (-0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. -0.75t + 0.140625 + t2 = 6.25 + 0.140625 Reorder the terms: 0.140625 + -0.75t + t2 = 6.25 + 0.140625 Combine like terms: 6.25 + 0.140625 = 6.390625 0.140625 + -0.75t + t2 = 6.390625 Factor a perfect square on the left side: (t + -0.375)(t + -0.375) = 6.390625 Calculate the square root of the right side: 2.527968552 Break this problem into two subproblems by setting (t + -0.375) equal to 2.527968552 and -2.527968552.Subproblem 1
t + -0.375 = 2.527968552 Simplifying t + -0.375 = 2.527968552 Reorder the terms: -0.375 + t = 2.527968552 Solving -0.375 + t = 2.527968552 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.375' to each side of the equation. -0.375 + 0.375 + t = 2.527968552 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + t = 2.527968552 + 0.375 t = 2.527968552 + 0.375 Combine like terms: 2.527968552 + 0.375 = 2.902968552 t = 2.902968552 Simplifying t = 2.902968552Subproblem 2
t + -0.375 = -2.527968552 Simplifying t + -0.375 = -2.527968552 Reorder the terms: -0.375 + t = -2.527968552 Solving -0.375 + t = -2.527968552 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '0.375' to each side of the equation. -0.375 + 0.375 + t = -2.527968552 + 0.375 Combine like terms: -0.375 + 0.375 = 0.000 0.000 + t = -2.527968552 + 0.375 t = -2.527968552 + 0.375 Combine like terms: -2.527968552 + 0.375 = -2.152968552 t = -2.152968552 Simplifying t = -2.152968552Solution
