Simplifying p2 + -8p + 21 = 0 Reorder the terms: 21 + -8p + p2 = 0 Solving 21 + -8p + p2 = 0 Solving for variable 'p'. Begin completing the square. Move the constant term to the right: Add '-21' to each side of the equation. 21 + -8p + -21 + p2 = 0 + -21 Reorder the terms: 21 + -21 + -8p + p2 = 0 + -21 Combine like terms: 21 + -21 = 0 0 + -8p + p2 = 0 + -21 -8p + p2 = 0 + -21 Combine like terms: 0 + -21 = -21 -8p + p2 = -21 The p term is -8p. Take half its coefficient (-4). Square it (16) and add it to both sides. Add '16' to each side of the equation. -8p + 16 + p2 = -21 + 16 Reorder the terms: 16 + -8p + p2 = -21 + 16 Combine like terms: -21 + 16 = -5 16 + -8p + p2 = -5 Factor a perfect square on the left side: (p + -4)(p + -4) = -5 Can't calculate square root of the right side. The solution to this equation could not be determined.
