Simplifying p2 + 2p + -31 = 0 Reorder the terms: -31 + 2p + p2 = 0 Solving -31 + 2p + p2 = 0 Solving for variable 'p'. Begin completing the square. Move the constant term to the right: Add '31' to each side of the equation. -31 + 2p + 31 + p2 = 0 + 31 Reorder the terms: -31 + 31 + 2p + p2 = 0 + 31 Combine like terms: -31 + 31 = 0 0 + 2p + p2 = 0 + 31 2p + p2 = 0 + 31 Combine like terms: 0 + 31 = 31 2p + p2 = 31 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 = 31 + 1 Reorder the terms: 1 + 2p + p2 = 31 + 1 Combine like terms: 31 + 1 = 32 1 + 2p + p2 = 32 Factor a perfect square on the left side: (p + 1)(p + 1) = 32 Calculate the square root of the right side: 5.656854249 Break this problem into two subproblems by setting (p + 1) equal to 5.656854249 and -5.656854249.Subproblem 1
p + 1 = 5.656854249 Simplifying p + 1 = 5.656854249 Reorder the terms: 1 + p = 5.656854249 Solving 1 + p = 5.656854249 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + p = 5.656854249 + -1 Combine like terms: 1 + -1 = 0 0 + p = 5.656854249 + -1 p = 5.656854249 + -1 Combine like terms: 5.656854249 + -1 = 4.656854249 p = 4.656854249 Simplifying p = 4.656854249Subproblem 2
p + 1 = -5.656854249 Simplifying p + 1 = -5.656854249 Reorder the terms: 1 + p = -5.656854249 Solving 1 + p = -5.656854249 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + p = -5.656854249 + -1 Combine like terms: 1 + -1 = 0 0 + p = -5.656854249 + -1 p = -5.656854249 + -1 Combine like terms: -5.656854249 + -1 = -6.656854249 p = -6.656854249 Simplifying p = -6.656854249Solution
