Simplifying x2 + -2x + 49 = 11x + 6 Reorder the terms: 49 + -2x + x2 = 11x + 6 Reorder the terms: 49 + -2x + x2 = 6 + 11x Solving 49 + -2x + x2 = 6 + 11x Solving for variable 'x'. Reorder the terms: 49 + -6 + -2x + -11x + x2 = 6 + 11x + -6 + -11x Combine like terms: 49 + -6 = 43 43 + -2x + -11x + x2 = 6 + 11x + -6 + -11x Combine like terms: -2x + -11x = -13x 43 + -13x + x2 = 6 + 11x + -6 + -11x Reorder the terms: 43 + -13x + x2 = 6 + -6 + 11x + -11x Combine like terms: 6 + -6 = 0 43 + -13x + x2 = 0 + 11x + -11x 43 + -13x + x2 = 11x + -11x Combine like terms: 11x + -11x = 0 43 + -13x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-43' to each side of the equation. 43 + -13x + -43 + x2 = 0 + -43 Reorder the terms: 43 + -43 + -13x + x2 = 0 + -43 Combine like terms: 43 + -43 = 0 0 + -13x + x2 = 0 + -43 -13x + x2 = 0 + -43 Combine like terms: 0 + -43 = -43 -13x + x2 = -43 The x term is -13x. Take half its coefficient (-6.5). Square it (42.25) and add it to both sides. Add '42.25' to each side of the equation. -13x + 42.25 + x2 = -43 + 42.25 Reorder the terms: 42.25 + -13x + x2 = -43 + 42.25 Combine like terms: -43 + 42.25 = -0.75 42.25 + -13x + x2 = -0.75 Factor a perfect square on the left side: (x + -6.5)(x + -6.5) = -0.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
