Simplifying t2 + 9t + -18 = 0 Reorder the terms: -18 + 9t + t2 = 0 Solving -18 + 9t + t2 = 0 Solving for variable 't'. Begin completing the square. Move the constant term to the right: Add '18' to each side of the equation. -18 + 9t + 18 + t2 = 0 + 18 Reorder the terms: -18 + 18 + 9t + t2 = 0 + 18 Combine like terms: -18 + 18 = 0 0 + 9t + t2 = 0 + 18 9t + t2 = 0 + 18 Combine like terms: 0 + 18 = 18 9t + t2 = 18 The t term is 9t. Take half its coefficient (4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. 9t + 20.25 + t2 = 18 + 20.25 Reorder the terms: 20.25 + 9t + t2 = 18 + 20.25 Combine like terms: 18 + 20.25 = 38.25 20.25 + 9t + t2 = 38.25 Factor a perfect square on the left side: (t + 4.5)(t + 4.5) = 38.25 Calculate the square root of the right side: 6.184658438 Break this problem into two subproblems by setting (t + 4.5) equal to 6.184658438 and -6.184658438.Subproblem 1
t + 4.5 = 6.184658438 Simplifying t + 4.5 = 6.184658438 Reorder the terms: 4.5 + t = 6.184658438 Solving 4.5 + t = 6.184658438 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + t = 6.184658438 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + t = 6.184658438 + -4.5 t = 6.184658438 + -4.5 Combine like terms: 6.184658438 + -4.5 = 1.684658438 t = 1.684658438 Simplifying t = 1.684658438Subproblem 2
t + 4.5 = -6.184658438 Simplifying t + 4.5 = -6.184658438 Reorder the terms: 4.5 + t = -6.184658438 Solving 4.5 + t = -6.184658438 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + t = -6.184658438 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + t = -6.184658438 + -4.5 t = -6.184658438 + -4.5 Combine like terms: -6.184658438 + -4.5 = -10.684658438 t = -10.684658438 Simplifying t = -10.684658438Solution
