Simplifying 4x2 + 28x + 39 = 0 Reorder the terms: 39 + 28x + 4x2 = 0 Solving 39 + 28x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 9.75 + 7x + x2 = 0 Move the constant term to the right: Add '-9.75' to each side of the equation. 9.75 + 7x + -9.75 + x2 = 0 + -9.75 Reorder the terms: 9.75 + -9.75 + 7x + x2 = 0 + -9.75 Combine like terms: 9.75 + -9.75 = 0.00 0.00 + 7x + x2 = 0 + -9.75 7x + x2 = 0 + -9.75 Combine like terms: 0 + -9.75 = -9.75 7x + x2 = -9.75 The x term is 7x. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7x + 12.25 + x2 = -9.75 + 12.25 Reorder the terms: 12.25 + 7x + x2 = -9.75 + 12.25 Combine like terms: -9.75 + 12.25 = 2.5 12.25 + 7x + x2 = 2.5 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 2.5 Calculate the square root of the right side: 1.58113883 Break this problem into two subproblems by setting (x + 3.5) equal to 1.58113883 and -1.58113883.Subproblem 1
x + 3.5 = 1.58113883 Simplifying x + 3.5 = 1.58113883 Reorder the terms: 3.5 + x = 1.58113883 Solving 3.5 + x = 1.58113883 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = 1.58113883 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 1.58113883 + -3.5 x = 1.58113883 + -3.5 Combine like terms: 1.58113883 + -3.5 = -1.91886117 x = -1.91886117 Simplifying x = -1.91886117Subproblem 2
x + 3.5 = -1.58113883 Simplifying x + 3.5 = -1.58113883 Reorder the terms: 3.5 + x = -1.58113883 Solving 3.5 + x = -1.58113883 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = -1.58113883 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -1.58113883 + -3.5 x = -1.58113883 + -3.5 Combine like terms: -1.58113883 + -3.5 = -5.08113883 x = -5.08113883 Simplifying x = -5.08113883Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.91886117, -5.08113883}
