Simplifying x2 = -4x + -13 Reorder the terms: x2 = -13 + -4x Solving x2 = -13 + -4x Solving for variable 'x'. Reorder the terms: 13 + 4x + x2 = -13 + -4x + 13 + 4x Reorder the terms: 13 + 4x + x2 = -13 + 13 + -4x + 4x Combine like terms: -13 + 13 = 0 13 + 4x + x2 = 0 + -4x + 4x 13 + 4x + x2 = -4x + 4x Combine like terms: -4x + 4x = 0 13 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-13' to each side of the equation. 13 + 4x + -13 + x2 = 0 + -13 Reorder the terms: 13 + -13 + 4x + x2 = 0 + -13 Combine like terms: 13 + -13 = 0 0 + 4x + x2 = 0 + -13 4x + x2 = 0 + -13 Combine like terms: 0 + -13 = -13 4x + x2 = -13 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 = -13 + 4 Reorder the terms: 4 + 4x + x2 = -13 + 4 Combine like terms: -13 + 4 = -9 4 + 4x + x2 = -9 Factor a perfect square on the left side: (x + 2)(x + 2) = -9 Can't calculate square root of the right side. The solution to this equation could not be determined.
