Simplifying 4x2 + -23x + -11 = 0 Reorder the terms: -11 + -23x + 4x2 = 0 Solving -11 + -23x + 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'. -2.75 + -5.75x + x2 = 0 Move the constant term to the right: Add '2.75' to each side of the equation. -2.75 + -5.75x + 2.75 + x2 = 0 + 2.75 Reorder the terms: -2.75 + 2.75 + -5.75x + x2 = 0 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + -5.75x + x2 = 0 + 2.75 -5.75x + x2 = 0 + 2.75 Combine like terms: 0 + 2.75 = 2.75 -5.75x + x2 = 2.75 The x term is -5.75x. Take half its coefficient (-2.875). Square it (8.265625) and add it to both sides. Add '8.265625' to each side of the equation. -5.75x + 8.265625 + x2 = 2.75 + 8.265625 Reorder the terms: 8.265625 + -5.75x + x2 = 2.75 + 8.265625 Combine like terms: 2.75 + 8.265625 = 11.015625 8.265625 + -5.75x + x2 = 11.015625 Factor a perfect square on the left side: (x + -2.875)(x + -2.875) = 11.015625 Calculate the square root of the right side: 3.318979512 Break this problem into two subproblems by setting (x + -2.875) equal to 3.318979512 and -3.318979512.Subproblem 1
x + -2.875 = 3.318979512 Simplifying x + -2.875 = 3.318979512 Reorder the terms: -2.875 + x = 3.318979512 Solving -2.875 + x = 3.318979512 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.875' to each side of the equation. -2.875 + 2.875 + x = 3.318979512 + 2.875 Combine like terms: -2.875 + 2.875 = 0.000 0.000 + x = 3.318979512 + 2.875 x = 3.318979512 + 2.875 Combine like terms: 3.318979512 + 2.875 = 6.193979512 x = 6.193979512 Simplifying x = 6.193979512Subproblem 2
x + -2.875 = -3.318979512 Simplifying x + -2.875 = -3.318979512 Reorder the terms: -2.875 + x = -3.318979512 Solving -2.875 + x = -3.318979512 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.875' to each side of the equation. -2.875 + 2.875 + x = -3.318979512 + 2.875 Combine like terms: -2.875 + 2.875 = 0.000 0.000 + x = -3.318979512 + 2.875 x = -3.318979512 + 2.875 Combine like terms: -3.318979512 + 2.875 = -0.443979512 x = -0.443979512 Simplifying x = -0.443979512Solution
