Simplifying 2x2 + -7x + -88 = 0 Reorder the terms: -88 + -7x + 2x2 = 0 Solving -88 + -7x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -44 + -3.5x + x2 = 0 Move the constant term to the right: Add '44' to each side of the equation. -44 + -3.5x + 44 + x2 = 0 + 44 Reorder the terms: -44 + 44 + -3.5x + x2 = 0 + 44 Combine like terms: -44 + 44 = 0 0 + -3.5x + x2 = 0 + 44 -3.5x + x2 = 0 + 44 Combine like terms: 0 + 44 = 44 -3.5x + x2 = 44 The x term is -3.5x. Take half its coefficient (-1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. -3.5x + 3.0625 + x2 = 44 + 3.0625 Reorder the terms: 3.0625 + -3.5x + x2 = 44 + 3.0625 Combine like terms: 44 + 3.0625 = 47.0625 3.0625 + -3.5x + x2 = 47.0625 Factor a perfect square on the left side: (x + -1.75)(x + -1.75) = 47.0625 Calculate the square root of the right side: 6.860211367 Break this problem into two subproblems by setting (x + -1.75) equal to 6.860211367 and -6.860211367.Subproblem 1
x + -1.75 = 6.860211367 Simplifying x + -1.75 = 6.860211367 Reorder the terms: -1.75 + x = 6.860211367 Solving -1.75 + x = 6.860211367 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.75' to each side of the equation. -1.75 + 1.75 + x = 6.860211367 + 1.75 Combine like terms: -1.75 + 1.75 = 0.00 0.00 + x = 6.860211367 + 1.75 x = 6.860211367 + 1.75 Combine like terms: 6.860211367 + 1.75 = 8.610211367 x = 8.610211367 Simplifying x = 8.610211367Subproblem 2
x + -1.75 = -6.860211367 Simplifying x + -1.75 = -6.860211367 Reorder the terms: -1.75 + x = -6.860211367 Solving -1.75 + x = -6.860211367 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.75' to each side of the equation. -1.75 + 1.75 + x = -6.860211367 + 1.75 Combine like terms: -1.75 + 1.75 = 0.00 0.00 + x = -6.860211367 + 1.75 x = -6.860211367 + 1.75 Combine like terms: -6.860211367 + 1.75 = -5.110211367 x = -5.110211367 Simplifying x = -5.110211367Solution
