Simplifying p2 + 2p + 7 = 0 Reorder the terms: 7 + 2p + p2 = 0 Solving 7 + 2p + p2 = 0 Solving for variable 'p'. Begin completing the square. Move the constant term to the right: Add '-7' to each side of the equation. 7 + 2p + -7 + p2 = 0 + -7 Reorder the terms: 7 + -7 + 2p + p2 = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 2p + p2 = 0 + -7 2p + p2 = 0 + -7 Combine like terms: 0 + -7 = -7 2p + p2 = -7 The p term is 2p. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2p + 1 + p2 = -7 + 1 Reorder the terms: 1 + 2p + p2 = -7 + 1 Combine like terms: -7 + 1 = -6 1 + 2p + p2 = -6 Factor a perfect square on the left side: (p + 1)(p + 1) = -6 Can't calculate square root of the right side. The solution to this equation could not be determined.
