Simplifying x2 + -23x + 110 = 0 Reorder the terms: 110 + -23x + x2 = 0 Solving 110 + -23x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-110' to each side of the equation. 110 + -23x + -110 + x2 = 0 + -110 Reorder the terms: 110 + -110 + -23x + x2 = 0 + -110 Combine like terms: 110 + -110 = 0 0 + -23x + x2 = 0 + -110 -23x + x2 = 0 + -110 Combine like terms: 0 + -110 = -110 -23x + x2 = -110 The x term is -23x. Take half its coefficient (-11.5). Square it (132.25) and add it to both sides. Add '132.25' to each side of the equation. -23x + 132.25 + x2 = -110 + 132.25 Reorder the terms: 132.25 + -23x + x2 = -110 + 132.25 Combine like terms: -110 + 132.25 = 22.25 132.25 + -23x + x2 = 22.25 Factor a perfect square on the left side: (x + -11.5)(x + -11.5) = 22.25 Calculate the square root of the right side: 4.716990566 Break this problem into two subproblems by setting (x + -11.5) equal to 4.716990566 and -4.716990566.Subproblem 1
x + -11.5 = 4.716990566 Simplifying x + -11.5 = 4.716990566 Reorder the terms: -11.5 + x = 4.716990566 Solving -11.5 + x = 4.716990566 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '11.5' to each side of the equation. -11.5 + 11.5 + x = 4.716990566 + 11.5 Combine like terms: -11.5 + 11.5 = 0.0 0.0 + x = 4.716990566 + 11.5 x = 4.716990566 + 11.5 Combine like terms: 4.716990566 + 11.5 = 16.216990566 x = 16.216990566 Simplifying x = 16.216990566Subproblem 2
x + -11.5 = -4.716990566 Simplifying x + -11.5 = -4.716990566 Reorder the terms: -11.5 + x = -4.716990566 Solving -11.5 + x = -4.716990566 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '11.5' to each side of the equation. -11.5 + 11.5 + x = -4.716990566 + 11.5 Combine like terms: -11.5 + 11.5 = 0.0 0.0 + x = -4.716990566 + 11.5 x = -4.716990566 + 11.5 Combine like terms: -4.716990566 + 11.5 = 6.783009434 x = 6.783009434 Simplifying x = 6.783009434Solution
