Simplifying 4t2 + -15t + -30 = 0 Reorder the terms: -30 + -15t + 4t2 = 0 Solving -30 + -15t + 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'. -7.5 + -3.75t + t2 = 0 Move the constant term to the right: Add '7.5' to each side of the equation. -7.5 + -3.75t + 7.5 + t2 = 0 + 7.5 Reorder the terms: -7.5 + 7.5 + -3.75t + t2 = 0 + 7.5 Combine like terms: -7.5 + 7.5 = 0.0 0.0 + -3.75t + t2 = 0 + 7.5 -3.75t + t2 = 0 + 7.5 Combine like terms: 0 + 7.5 = 7.5 -3.75t + t2 = 7.5 The t term is -3.75t. Take half its coefficient (-1.875). Square it (3.515625) and add it to both sides. Add '3.515625' to each side of the equation. -3.75t + 3.515625 + t2 = 7.5 + 3.515625 Reorder the terms: 3.515625 + -3.75t + t2 = 7.5 + 3.515625 Combine like terms: 7.5 + 3.515625 = 11.015625 3.515625 + -3.75t + t2 = 11.015625 Factor a perfect square on the left side: (t + -1.875)(t + -1.875) = 11.015625 Calculate the square root of the right side: 3.318979512 Break this problem into two subproblems by setting (t + -1.875) equal to 3.318979512 and -3.318979512.Subproblem 1
t + -1.875 = 3.318979512 Simplifying t + -1.875 = 3.318979512 Reorder the terms: -1.875 + t = 3.318979512 Solving -1.875 + t = 3.318979512 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.875' to each side of the equation. -1.875 + 1.875 + t = 3.318979512 + 1.875 Combine like terms: -1.875 + 1.875 = 0.000 0.000 + t = 3.318979512 + 1.875 t = 3.318979512 + 1.875 Combine like terms: 3.318979512 + 1.875 = 5.193979512 t = 5.193979512 Simplifying t = 5.193979512Subproblem 2
t + -1.875 = -3.318979512 Simplifying t + -1.875 = -3.318979512 Reorder the terms: -1.875 + t = -3.318979512 Solving -1.875 + t = -3.318979512 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.875' to each side of the equation. -1.875 + 1.875 + t = -3.318979512 + 1.875 Combine like terms: -1.875 + 1.875 = 0.000 0.000 + t = -3.318979512 + 1.875 t = -3.318979512 + 1.875 Combine like terms: -3.318979512 + 1.875 = -1.443979512 t = -1.443979512 Simplifying t = -1.443979512Solution
