Simplifying p2 + -18p + 270 = 0 Reorder the terms: 270 + -18p + p2 = 0 Solving 270 + -18p + p2 = 0 Solving for variable 'p'. Begin completing the square. Move the constant term to the right: Add '-270' to each side of the equation. 270 + -18p + -270 + p2 = 0 + -270 Reorder the terms: 270 + -270 + -18p + p2 = 0 + -270 Combine like terms: 270 + -270 = 0 0 + -18p + p2 = 0 + -270 -18p + p2 = 0 + -270 Combine like terms: 0 + -270 = -270 -18p + p2 = -270 The p term is -18p. Take half its coefficient (-9). Square it (81) and add it to both sides. Add '81' to each side of the equation. -18p + 81 + p2 = -270 + 81 Reorder the terms: 81 + -18p + p2 = -270 + 81 Combine like terms: -270 + 81 = -189 81 + -18p + p2 = -189 Factor a perfect square on the left side: (p + -9)(p + -9) = -189 Can't calculate square root of the right side. The solution to this equation could not be determined.
