Simplifying x2 + -3x + -31 = 2 Reorder the terms: -31 + -3x + x2 = 2 Solving -31 + -3x + x2 = 2 Solving for variable 'x'. Reorder the terms: -31 + -2 + -3x + x2 = 2 + -2 Combine like terms: -31 + -2 = -33 -33 + -3x + x2 = 2 + -2 Combine like terms: 2 + -2 = 0 -33 + -3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '33' to each side of the equation. -33 + -3x + 33 + x2 = 0 + 33 Reorder the terms: -33 + 33 + -3x + x2 = 0 + 33 Combine like terms: -33 + 33 = 0 0 + -3x + x2 = 0 + 33 -3x + x2 = 0 + 33 Combine like terms: 0 + 33 = 33 -3x + x2 = 33 The x term is -3x. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3x + 2.25 + x2 = 33 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 33 + 2.25 Combine like terms: 33 + 2.25 = 35.25 2.25 + -3x + x2 = 35.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 35.25 Calculate the square root of the right side: 5.937171044 Break this problem into two subproblems by setting (x + -1.5) equal to 5.937171044 and -5.937171044.Subproblem 1
x + -1.5 = 5.937171044 Simplifying x + -1.5 = 5.937171044 Reorder the terms: -1.5 + x = 5.937171044 Solving -1.5 + x = 5.937171044 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = 5.937171044 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 5.937171044 + 1.5 x = 5.937171044 + 1.5 Combine like terms: 5.937171044 + 1.5 = 7.437171044 x = 7.437171044 Simplifying x = 7.437171044Subproblem 2
x + -1.5 = -5.937171044 Simplifying x + -1.5 = -5.937171044 Reorder the terms: -1.5 + x = -5.937171044 Solving -1.5 + x = -5.937171044 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = -5.937171044 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -5.937171044 + 1.5 x = -5.937171044 + 1.5 Combine like terms: -5.937171044 + 1.5 = -4.437171044 x = -4.437171044 Simplifying x = -4.437171044Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.437171044, -4.437171044}
