Simplifying 4x2 + 4x = 736 Reorder the terms: 4x + 4x2 = 736 Solving 4x + 4x2 = 736 Solving for variable 'x'. Reorder the terms: -736 + 4x + 4x2 = 736 + -736 Combine like terms: 736 + -736 = 0 -736 + 4x + 4x2 = 0 Factor out the Greatest Common Factor (GCF), '4'. 4(-184 + x + x2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(-184 + x + x2)' equal to zero and attempt to solve: Simplifying -184 + x + x2 = 0 Solving -184 + x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '184' to each side of the equation. -184 + x + 184 + x2 = 0 + 184 Reorder the terms: -184 + 184 + x + x2 = 0 + 184 Combine like terms: -184 + 184 = 0 0 + x + x2 = 0 + 184 x + x2 = 0 + 184 Combine like terms: 0 + 184 = 184 x + x2 = 184 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. x + 0.25 + x2 = 184 + 0.25 Reorder the terms: 0.25 + x + x2 = 184 + 0.25 Combine like terms: 184 + 0.25 = 184.25 0.25 + x + x2 = 184.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 184.25 Calculate the square root of the right side: 13.57387196 Break this problem into two subproblems by setting (x + 0.5) equal to 13.57387196 and -13.57387196.Subproblem 1
x + 0.5 = 13.57387196 Simplifying x + 0.5 = 13.57387196 Reorder the terms: 0.5 + x = 13.57387196 Solving 0.5 + x = 13.57387196 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 13.57387196 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 13.57387196 + -0.5 x = 13.57387196 + -0.5 Combine like terms: 13.57387196 + -0.5 = 13.07387196 x = 13.07387196 Simplifying x = 13.07387196Subproblem 2
x + 0.5 = -13.57387196 Simplifying x + 0.5 = -13.57387196 Reorder the terms: 0.5 + x = -13.57387196 Solving 0.5 + x = -13.57387196 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -13.57387196 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -13.57387196 + -0.5 x = -13.57387196 + -0.5 Combine like terms: -13.57387196 + -0.5 = -14.07387196 x = -14.07387196 Simplifying x = -14.07387196Solution
The solution to the problem is based on the solutions from the subproblems. x = {13.07387196, -14.07387196}Solution
x = {13.07387196, -14.07387196}
