Simplifying 4x2 + 13x + 12 = 49 Reorder the terms: 12 + 13x + 4x2 = 49 Solving 12 + 13x + 4x2 = 49 Solving for variable 'x'. Reorder the terms: 12 + -49 + 13x + 4x2 = 49 + -49 Combine like terms: 12 + -49 = -37 -37 + 13x + 4x2 = 49 + -49 Combine like terms: 49 + -49 = 0 -37 + 13x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -9.25 + 3.25x + x2 = 0 Move the constant term to the right: Add '9.25' to each side of the equation. -9.25 + 3.25x + 9.25 + x2 = 0 + 9.25 Reorder the terms: -9.25 + 9.25 + 3.25x + x2 = 0 + 9.25 Combine like terms: -9.25 + 9.25 = 0.00 0.00 + 3.25x + x2 = 0 + 9.25 3.25x + x2 = 0 + 9.25 Combine like terms: 0 + 9.25 = 9.25 3.25x + x2 = 9.25 The x term is 3.25x. Take half its coefficient (1.625). Square it (2.640625) and add it to both sides. Add '2.640625' to each side of the equation. 3.25x + 2.640625 + x2 = 9.25 + 2.640625 Reorder the terms: 2.640625 + 3.25x + x2 = 9.25 + 2.640625 Combine like terms: 9.25 + 2.640625 = 11.890625 2.640625 + 3.25x + x2 = 11.890625 Factor a perfect square on the left side: (x + 1.625)(x + 1.625) = 11.890625 Calculate the square root of the right side: 3.448278556 Break this problem into two subproblems by setting (x + 1.625) equal to 3.448278556 and -3.448278556.Subproblem 1
x + 1.625 = 3.448278556 Simplifying x + 1.625 = 3.448278556 Reorder the terms: 1.625 + x = 3.448278556 Solving 1.625 + x = 3.448278556 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.625' to each side of the equation. 1.625 + -1.625 + x = 3.448278556 + -1.625 Combine like terms: 1.625 + -1.625 = 0.000 0.000 + x = 3.448278556 + -1.625 x = 3.448278556 + -1.625 Combine like terms: 3.448278556 + -1.625 = 1.823278556 x = 1.823278556 Simplifying x = 1.823278556Subproblem 2
x + 1.625 = -3.448278556 Simplifying x + 1.625 = -3.448278556 Reorder the terms: 1.625 + x = -3.448278556 Solving 1.625 + x = -3.448278556 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.625' to each side of the equation. 1.625 + -1.625 + x = -3.448278556 + -1.625 Combine like terms: 1.625 + -1.625 = 0.000 0.000 + x = -3.448278556 + -1.625 x = -3.448278556 + -1.625 Combine like terms: -3.448278556 + -1.625 = -5.073278556 x = -5.073278556 Simplifying x = -5.073278556Solution
