Simplifying x2 + -11x + 19 = -2 Reorder the terms: 19 + -11x + x2 = -2 Solving 19 + -11x + x2 = -2 Solving for variable 'x'. Reorder the terms: 19 + 2 + -11x + x2 = -2 + 2 Combine like terms: 19 + 2 = 21 21 + -11x + x2 = -2 + 2 Combine like terms: -2 + 2 = 0 21 + -11x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-21' to each side of the equation. 21 + -11x + -21 + x2 = 0 + -21 Reorder the terms: 21 + -21 + -11x + x2 = 0 + -21 Combine like terms: 21 + -21 = 0 0 + -11x + x2 = 0 + -21 -11x + x2 = 0 + -21 Combine like terms: 0 + -21 = -21 -11x + x2 = -21 The x term is -11x. Take half its coefficient (-5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. -11x + 30.25 + x2 = -21 + 30.25 Reorder the terms: 30.25 + -11x + x2 = -21 + 30.25 Combine like terms: -21 + 30.25 = 9.25 30.25 + -11x + x2 = 9.25 Factor a perfect square on the left side: (x + -5.5)(x + -5.5) = 9.25 Calculate the square root of the right side: 3.041381265 Break this problem into two subproblems by setting (x + -5.5) equal to 3.041381265 and -3.041381265.Subproblem 1
x + -5.5 = 3.041381265 Simplifying x + -5.5 = 3.041381265 Reorder the terms: -5.5 + x = 3.041381265 Solving -5.5 + x = 3.041381265 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5.5' to each side of the equation. -5.5 + 5.5 + x = 3.041381265 + 5.5 Combine like terms: -5.5 + 5.5 = 0.0 0.0 + x = 3.041381265 + 5.5 x = 3.041381265 + 5.5 Combine like terms: 3.041381265 + 5.5 = 8.541381265 x = 8.541381265 Simplifying x = 8.541381265Subproblem 2
x + -5.5 = -3.041381265 Simplifying x + -5.5 = -3.041381265 Reorder the terms: -5.5 + x = -3.041381265 Solving -5.5 + x = -3.041381265 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5.5' to each side of the equation. -5.5 + 5.5 + x = -3.041381265 + 5.5 Combine like terms: -5.5 + 5.5 = 0.0 0.0 + x = -3.041381265 + 5.5 x = -3.041381265 + 5.5 Combine like terms: -3.041381265 + 5.5 = 2.458618735 x = 2.458618735 Simplifying x = 2.458618735Solution
