Simplifying 4t2 + -18t + -21 = 0 Reorder the terms: -21 + -18t + 4t2 = 0 Solving -21 + -18t + 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'. -5.25 + -4.5t + t2 = 0 Move the constant term to the right: Add '5.25' to each side of the equation. -5.25 + -4.5t + 5.25 + t2 = 0 + 5.25 Reorder the terms: -5.25 + 5.25 + -4.5t + t2 = 0 + 5.25 Combine like terms: -5.25 + 5.25 = 0.00 0.00 + -4.5t + t2 = 0 + 5.25 -4.5t + t2 = 0 + 5.25 Combine like terms: 0 + 5.25 = 5.25 -4.5t + t2 = 5.25 The t term is -4.5t. Take half its coefficient (-2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. -4.5t + 5.0625 + t2 = 5.25 + 5.0625 Reorder the terms: 5.0625 + -4.5t + t2 = 5.25 + 5.0625 Combine like terms: 5.25 + 5.0625 = 10.3125 5.0625 + -4.5t + t2 = 10.3125 Factor a perfect square on the left side: (t + -2.25)(t + -2.25) = 10.3125 Calculate the square root of the right side: 3.211308145 Break this problem into two subproblems by setting (t + -2.25) equal to 3.211308145 and -3.211308145.Subproblem 1
t + -2.25 = 3.211308145 Simplifying t + -2.25 = 3.211308145 Reorder the terms: -2.25 + t = 3.211308145 Solving -2.25 + t = 3.211308145 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '2.25' to each side of the equation. -2.25 + 2.25 + t = 3.211308145 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + t = 3.211308145 + 2.25 t = 3.211308145 + 2.25 Combine like terms: 3.211308145 + 2.25 = 5.461308145 t = 5.461308145 Simplifying t = 5.461308145Subproblem 2
t + -2.25 = -3.211308145 Simplifying t + -2.25 = -3.211308145 Reorder the terms: -2.25 + t = -3.211308145 Solving -2.25 + t = -3.211308145 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '2.25' to each side of the equation. -2.25 + 2.25 + t = -3.211308145 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + t = -3.211308145 + 2.25 t = -3.211308145 + 2.25 Combine like terms: -3.211308145 + 2.25 = -0.961308145 t = -0.961308145 Simplifying t = -0.961308145Solution
