Simplifying x2 + 33x + 656 = 0 Reorder the terms: 656 + 33x + x2 = 0 Solving 656 + 33x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-656' to each side of the equation. 656 + 33x + -656 + x2 = 0 + -656 Reorder the terms: 656 + -656 + 33x + x2 = 0 + -656 Combine like terms: 656 + -656 = 0 0 + 33x + x2 = 0 + -656 33x + x2 = 0 + -656 Combine like terms: 0 + -656 = -656 33x + x2 = -656 The x term is 33x. Take half its coefficient (16.5). Square it (272.25) and add it to both sides. Add '272.25' to each side of the equation. 33x + 272.25 + x2 = -656 + 272.25 Reorder the terms: 272.25 + 33x + x2 = -656 + 272.25 Combine like terms: -656 + 272.25 = -383.75 272.25 + 33x + x2 = -383.75 Factor a perfect square on the left side: (x + 16.5)(x + 16.5) = -383.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
