Simplifying x2 = -2x + -8 Reorder the terms: x2 = -8 + -2x Solving x2 = -8 + -2x Solving for variable 'x'. Reorder the terms: 8 + 2x + x2 = -8 + -2x + 8 + 2x Reorder the terms: 8 + 2x + x2 = -8 + 8 + -2x + 2x Combine like terms: -8 + 8 = 0 8 + 2x + x2 = 0 + -2x + 2x 8 + 2x + x2 = -2x + 2x Combine like terms: -2x + 2x = 0 8 + 2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-8' to each side of the equation. 8 + 2x + -8 + x2 = 0 + -8 Reorder the terms: 8 + -8 + 2x + x2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + 2x + x2 = 0 + -8 2x + x2 = 0 + -8 Combine like terms: 0 + -8 = -8 2x + x2 = -8 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = -8 + 1 Reorder the terms: 1 + 2x + x2 = -8 + 1 Combine like terms: -8 + 1 = -7 1 + 2x + x2 = -7 Factor a perfect square on the left side: (x + 1)(x + 1) = -7 Can't calculate square root of the right side. The solution to this equation could not be determined.
