Simplifying p2 + 28p = -33 Reorder the terms: 28p + p2 = -33 Solving 28p + p2 = -33 Solving for variable 'p'. Reorder the terms: 33 + 28p + p2 = -33 + 33 Combine like terms: -33 + 33 = 0 33 + 28p + p2 = 0 Begin completing the square. Move the constant term to the right: Add '-33' to each side of the equation. 33 + 28p + -33 + p2 = 0 + -33 Reorder the terms: 33 + -33 + 28p + p2 = 0 + -33 Combine like terms: 33 + -33 = 0 0 + 28p + p2 = 0 + -33 28p + p2 = 0 + -33 Combine like terms: 0 + -33 = -33 28p + p2 = -33 The p term is 28p. Take half its coefficient (14). Square it (196) and add it to both sides. Add '196' to each side of the equation. 28p + 196 + p2 = -33 + 196 Reorder the terms: 196 + 28p + p2 = -33 + 196 Combine like terms: -33 + 196 = 163 196 + 28p + p2 = 163 Factor a perfect square on the left side: (p + 14)(p + 14) = 163 Calculate the square root of the right side: 12.767145335 Break this problem into two subproblems by setting (p + 14) equal to 12.767145335 and -12.767145335.Subproblem 1
p + 14 = 12.767145335 Simplifying p + 14 = 12.767145335 Reorder the terms: 14 + p = 12.767145335 Solving 14 + p = 12.767145335 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '-14' to each side of the equation. 14 + -14 + p = 12.767145335 + -14 Combine like terms: 14 + -14 = 0 0 + p = 12.767145335 + -14 p = 12.767145335 + -14 Combine like terms: 12.767145335 + -14 = -1.232854665 p = -1.232854665 Simplifying p = -1.232854665Subproblem 2
p + 14 = -12.767145335 Simplifying p + 14 = -12.767145335 Reorder the terms: 14 + p = -12.767145335 Solving 14 + p = -12.767145335 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '-14' to each side of the equation. 14 + -14 + p = -12.767145335 + -14 Combine like terms: 14 + -14 = 0 0 + p = -12.767145335 + -14 p = -12.767145335 + -14 Combine like terms: -12.767145335 + -14 = -26.767145335 p = -26.767145335 Simplifying p = -26.767145335Solution
