Simplifying p2 + 4p = -13 Reorder the terms: 4p + p2 = -13 Solving 4p + p2 = -13 Solving for variable 'p'. Reorder the terms: 13 + 4p + p2 = -13 + 13 Combine like terms: -13 + 13 = 0 13 + 4p + p2 = 0 Begin completing the square. Move the constant term to the right: Add '-13' to each side of the equation. 13 + 4p + -13 + p2 = 0 + -13 Reorder the terms: 13 + -13 + 4p + p2 = 0 + -13 Combine like terms: 13 + -13 = 0 0 + 4p + p2 = 0 + -13 4p + p2 = 0 + -13 Combine like terms: 0 + -13 = -13 4p + p2 = -13 The p term is 4p. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4p + 4 + p2 = -13 + 4 Reorder the terms: 4 + 4p + p2 = -13 + 4 Combine like terms: -13 + 4 = -9 4 + 4p + p2 = -9 Factor a perfect square on the left side: (p + 2)(p + 2) = -9 Can't calculate square root of the right side. The solution to this equation could not be determined.
