Simplifying x * x + 2x + 48 = 0 Multiply x * x x2 + 2x + 48 = 0 Reorder the terms: 48 + 2x + x2 = 0 Solving 48 + 2x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-48' to each side of the equation. 48 + 2x + -48 + x2 = 0 + -48 Reorder the terms: 48 + -48 + 2x + x2 = 0 + -48 Combine like terms: 48 + -48 = 0 0 + 2x + x2 = 0 + -48 2x + x2 = 0 + -48 Combine like terms: 0 + -48 = -48 2x + x2 = -48 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 = -48 + 1 Reorder the terms: 1 + 2x + x2 = -48 + 1 Combine like terms: -48 + 1 = -47 1 + 2x + x2 = -47 Factor a perfect square on the left side: (x + 1)(x + 1) = -47 Can't calculate square root of the right side. The solution to this equation could not be determined.
