Simplifying x2 + 13 = 5x Reorder the terms: 13 + x2 = 5x Solving 13 + x2 = 5x Solving for variable 'x'. Reorder the terms: 13 + -5x + x2 = 5x + -5x Combine like terms: 5x + -5x = 0 13 + -5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-13' to each side of the equation. 13 + -5x + -13 + x2 = 0 + -13 Reorder the terms: 13 + -13 + -5x + x2 = 0 + -13 Combine like terms: 13 + -13 = 0 0 + -5x + x2 = 0 + -13 -5x + x2 = 0 + -13 Combine like terms: 0 + -13 = -13 -5x + x2 = -13 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = -13 + 6.25 Reorder the terms: 6.25 + -5x + x2 = -13 + 6.25 Combine like terms: -13 + 6.25 = -6.75 6.25 + -5x + x2 = -6.75 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = -6.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
