Simplifying x2 + -21x + 196 = 0 Reorder the terms: 196 + -21x + x2 = 0 Solving 196 + -21x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-196' to each side of the equation. 196 + -21x + -196 + x2 = 0 + -196 Reorder the terms: 196 + -196 + -21x + x2 = 0 + -196 Combine like terms: 196 + -196 = 0 0 + -21x + x2 = 0 + -196 -21x + x2 = 0 + -196 Combine like terms: 0 + -196 = -196 -21x + x2 = -196 The x term is -21x. Take half its coefficient (-10.5). Square it (110.25) and add it to both sides. Add '110.25' to each side of the equation. -21x + 110.25 + x2 = -196 + 110.25 Reorder the terms: 110.25 + -21x + x2 = -196 + 110.25 Combine like terms: -196 + 110.25 = -85.75 110.25 + -21x + x2 = -85.75 Factor a perfect square on the left side: (x + -10.5)(x + -10.5) = -85.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
