Simplifying -3u2 + -72u + -105 = 0 Reorder the terms: -105 + -72u + -3u2 = 0 Solving -105 + -72u + -3u2 = 0 Solving for variable 'u'. Factor out the Greatest Common Factor (GCF), '-3'. -3(35 + 24u + u2) = 0 Ignore the factor -3.Subproblem 1
Set the factor '(35 + 24u + u2)' equal to zero and attempt to solve: Simplifying 35 + 24u + u2 = 0 Solving 35 + 24u + u2 = 0 Begin completing the square. Move the constant term to the right: Add '-35' to each side of the equation. 35 + 24u + -35 + u2 = 0 + -35 Reorder the terms: 35 + -35 + 24u + u2 = 0 + -35 Combine like terms: 35 + -35 = 0 0 + 24u + u2 = 0 + -35 24u + u2 = 0 + -35 Combine like terms: 0 + -35 = -35 24u + u2 = -35 The u term is 24u. Take half its coefficient (12). Square it (144) and add it to both sides. Add '144' to each side of the equation. 24u + 144 + u2 = -35 + 144 Reorder the terms: 144 + 24u + u2 = -35 + 144 Combine like terms: -35 + 144 = 109 144 + 24u + u2 = 109 Factor a perfect square on the left side: (u + 12)(u + 12) = 109 Calculate the square root of the right side: 10.440306509 Break this problem into two subproblems by setting (u + 12) equal to 10.440306509 and -10.440306509.Subproblem 1
u + 12 = 10.440306509 Simplifying u + 12 = 10.440306509 Reorder the terms: 12 + u = 10.440306509 Solving 12 + u = 10.440306509 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + u = 10.440306509 + -12 Combine like terms: 12 + -12 = 0 0 + u = 10.440306509 + -12 u = 10.440306509 + -12 Combine like terms: 10.440306509 + -12 = -1.559693491 u = -1.559693491 Simplifying u = -1.559693491Subproblem 2
u + 12 = -10.440306509 Simplifying u + 12 = -10.440306509 Reorder the terms: 12 + u = -10.440306509 Solving 12 + u = -10.440306509 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + u = -10.440306509 + -12 Combine like terms: 12 + -12 = 0 0 + u = -10.440306509 + -12 u = -10.440306509 + -12 Combine like terms: -10.440306509 + -12 = -22.440306509 u = -22.440306509 Simplifying u = -22.440306509Solution
The solution to the problem is based on the solutions from the subproblems. u = {-1.559693491, -22.440306509}Solution
u = {-1.559693491, -22.440306509}
