Simplifying x(x + 4) = -84 Reorder the terms: x(4 + x) = -84 (4 * x + x * x) = -84 (4x + x2) = -84 Solving 4x + x2 = -84 Solving for variable 'x'. Reorder the terms: 84 + 4x + x2 = -84 + 84 Combine like terms: -84 + 84 = 0 84 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-84' to each side of the equation. 84 + 4x + -84 + x2 = 0 + -84 Reorder the terms: 84 + -84 + 4x + x2 = 0 + -84 Combine like terms: 84 + -84 = 0 0 + 4x + x2 = 0 + -84 4x + x2 = 0 + -84 Combine like terms: 0 + -84 = -84 4x + x2 = -84 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 = -84 + 4 Reorder the terms: 4 + 4x + x2 = -84 + 4 Combine like terms: -84 + 4 = -80 4 + 4x + x2 = -80 Factor a perfect square on the left side: (x + 2)(x + 2) = -80 Can't calculate square root of the right side. The solution to this equation could not be determined.
