Simplifying 3u2 + -12u + 3 = 0 Reorder the terms: 3 + -12u + 3u2 = 0 Solving 3 + -12u + 3u2 = 0 Solving for variable 'u'. Factor out the Greatest Common Factor (GCF), '3'. 3(1 + -4u + u2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(1 + -4u + u2)' equal to zero and attempt to solve: Simplifying 1 + -4u + u2 = 0 Solving 1 + -4u + u2 = 0 Begin completing the square. Move the constant term to the right: Add '-1' to each side of the equation. 1 + -4u + -1 + u2 = 0 + -1 Reorder the terms: 1 + -1 + -4u + u2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -4u + u2 = 0 + -1 -4u + u2 = 0 + -1 Combine like terms: 0 + -1 = -1 -4u + u2 = -1 The u term is -4u. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4u + 4 + u2 = -1 + 4 Reorder the terms: 4 + -4u + u2 = -1 + 4 Combine like terms: -1 + 4 = 3 4 + -4u + u2 = 3 Factor a perfect square on the left side: (u + -2)(u + -2) = 3 Calculate the square root of the right side: 1.732050808 Break this problem into two subproblems by setting (u + -2) equal to 1.732050808 and -1.732050808.Subproblem 1
u + -2 = 1.732050808 Simplifying u + -2 = 1.732050808 Reorder the terms: -2 + u = 1.732050808 Solving -2 + u = 1.732050808 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + u = 1.732050808 + 2 Combine like terms: -2 + 2 = 0 0 + u = 1.732050808 + 2 u = 1.732050808 + 2 Combine like terms: 1.732050808 + 2 = 3.732050808 u = 3.732050808 Simplifying u = 3.732050808Subproblem 2
u + -2 = -1.732050808 Simplifying u + -2 = -1.732050808 Reorder the terms: -2 + u = -1.732050808 Solving -2 + u = -1.732050808 Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + u = -1.732050808 + 2 Combine like terms: -2 + 2 = 0 0 + u = -1.732050808 + 2 u = -1.732050808 + 2 Combine like terms: -1.732050808 + 2 = 0.267949192 u = 0.267949192 Simplifying u = 0.267949192Solution
The solution to the problem is based on the solutions from the subproblems. u = {3.732050808, 0.267949192}Solution
u = {3.732050808, 0.267949192}
