Simplifying x2 + -4x = 22 Reorder the terms: -4x + x2 = 22 Solving -4x + x2 = 22 Solving for variable 'x'. Reorder the terms: -22 + -4x + x2 = 22 + -22 Combine like terms: 22 + -22 = 0 -22 + -4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '22' to each side of the equation. -22 + -4x + 22 + x2 = 0 + 22 Reorder the terms: -22 + 22 + -4x + x2 = 0 + 22 Combine like terms: -22 + 22 = 0 0 + -4x + x2 = 0 + 22 -4x + x2 = 0 + 22 Combine like terms: 0 + 22 = 22 -4x + x2 = 22 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = 22 + 4 Reorder the terms: 4 + -4x + x2 = 22 + 4 Combine like terms: 22 + 4 = 26 4 + -4x + x2 = 26 Factor a perfect square on the left side: (x + -2)(x + -2) = 26 Calculate the square root of the right side: 5.099019514 Break this problem into two subproblems by setting (x + -2) equal to 5.099019514 and -5.099019514.Subproblem 1
x + -2 = 5.099019514 Simplifying x + -2 = 5.099019514 Reorder the terms: -2 + x = 5.099019514 Solving -2 + x = 5.099019514 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = 5.099019514 + 2 Combine like terms: -2 + 2 = 0 0 + x = 5.099019514 + 2 x = 5.099019514 + 2 Combine like terms: 5.099019514 + 2 = 7.099019514 x = 7.099019514 Simplifying x = 7.099019514Subproblem 2
