Simplifying 3 = 2x2 + -11x Reorder the terms: 3 = -11x + 2x2 Solving 3 = -11x + 2x2 Solving for variable 'x'. Reorder the terms: 3 + 11x + -2x2 = -11x + 11x + 2x2 + -2x2 Combine like terms: -11x + 11x = 0 3 + 11x + -2x2 = 0 + 2x2 + -2x2 3 + 11x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 3 + 11x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -1.5 + -5.5x + x2 = 0 Move the constant term to the right: Add '1.5' to each side of the equation. -1.5 + -5.5x + 1.5 + x2 = 0 + 1.5 Reorder the terms: -1.5 + 1.5 + -5.5x + x2 = 0 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + -5.5x + x2 = 0 + 1.5 -5.5x + x2 = 0 + 1.5 Combine like terms: 0 + 1.5 = 1.5 -5.5x + x2 = 1.5 The x term is -5.5x. Take half its coefficient (-2.75). Square it (7.5625) and add it to both sides. Add '7.5625' to each side of the equation. -5.5x + 7.5625 + x2 = 1.5 + 7.5625 Reorder the terms: 7.5625 + -5.5x + x2 = 1.5 + 7.5625 Combine like terms: 1.5 + 7.5625 = 9.0625 7.5625 + -5.5x + x2 = 9.0625 Factor a perfect square on the left side: (x + -2.75)(x + -2.75) = 9.0625 Calculate the square root of the right side: 3.010398645 Break this problem into two subproblems by setting (x + -2.75) equal to 3.010398645 and -3.010398645.Subproblem 1
x + -2.75 = 3.010398645 Simplifying x + -2.75 = 3.010398645 Reorder the terms: -2.75 + x = 3.010398645 Solving -2.75 + x = 3.010398645 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.75' to each side of the equation. -2.75 + 2.75 + x = 3.010398645 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + x = 3.010398645 + 2.75 x = 3.010398645 + 2.75 Combine like terms: 3.010398645 + 2.75 = 5.760398645 x = 5.760398645 Simplifying x = 5.760398645Subproblem 2
x + -2.75 = -3.010398645 Simplifying x + -2.75 = -3.010398645 Reorder the terms: -2.75 + x = -3.010398645 Solving -2.75 + x = -3.010398645 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.75' to each side of the equation. -2.75 + 2.75 + x = -3.010398645 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + x = -3.010398645 + 2.75 x = -3.010398645 + 2.75 Combine like terms: -3.010398645 + 2.75 = -0.260398645 x = -0.260398645 Simplifying x = -0.260398645Solution
