Simplifying 4x2 + -13x = 3 Reorder the terms: -13x + 4x2 = 3 Solving -13x + 4x2 = 3 Solving for variable 'x'. Reorder the terms: -3 + -13x + 4x2 = 3 + -3 Combine like terms: 3 + -3 = 0 -3 + -13x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -0.75 + -3.25x + x2 = 0 Move the constant term to the right: Add '0.75' to each side of the equation. -0.75 + -3.25x + 0.75 + x2 = 0 + 0.75 Reorder the terms: -0.75 + 0.75 + -3.25x + x2 = 0 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + -3.25x + x2 = 0 + 0.75 -3.25x + x2 = 0 + 0.75 Combine like terms: 0 + 0.75 = 0.75 -3.25x + x2 = 0.75 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 = 0.75 + 2.640625 Reorder the terms: 2.640625 + -3.25x + x2 = 0.75 + 2.640625 Combine like terms: 0.75 + 2.640625 = 3.390625 2.640625 + -3.25x + x2 = 3.390625 Factor a perfect square on the left side: (x + -1.625)(x + -1.625) = 3.390625 Calculate the square root of the right side: 1.841364983 Break this problem into two subproblems by setting (x + -1.625) equal to 1.841364983 and -1.841364983.Subproblem 1
x + -1.625 = 1.841364983 Simplifying x + -1.625 = 1.841364983 Reorder the terms: -1.625 + x = 1.841364983 Solving -1.625 + x = 1.841364983 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 = 1.841364983 + 1.625 Combine like terms: -1.625 + 1.625 = 0.000 0.000 + x = 1.841364983 + 1.625 x = 1.841364983 + 1.625 Combine like terms: 1.841364983 + 1.625 = 3.466364983 x = 3.466364983 Simplifying x = 3.466364983Subproblem 2
x + -1.625 = -1.841364983 Simplifying x + -1.625 = -1.841364983 Reorder the terms: -1.625 + x = -1.841364983 Solving -1.625 + x = -1.841364983 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 = -1.841364983 + 1.625 Combine like terms: -1.625 + 1.625 = 0.000 0.000 + x = -1.841364983 + 1.625 x = -1.841364983 + 1.625 Combine like terms: -1.841364983 + 1.625 = -0.216364983 x = -0.216364983 Simplifying x = -0.216364983Solution
