Simplifying p2 + -14p + -1 = 4 Reorder the terms: -1 + -14p + p2 = 4 Solving -1 + -14p + p2 = 4 Solving for variable 'p'. Reorder the terms: -1 + -4 + -14p + p2 = 4 + -4 Combine like terms: -1 + -4 = -5 -5 + -14p + p2 = 4 + -4 Combine like terms: 4 + -4 = 0 -5 + -14p + p2 = 0 Begin completing the square. Move the constant term to the right: Add '5' to each side of the equation. -5 + -14p + 5 + p2 = 0 + 5 Reorder the terms: -5 + 5 + -14p + p2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + -14p + p2 = 0 + 5 -14p + p2 = 0 + 5 Combine like terms: 0 + 5 = 5 -14p + p2 = 5 The p term is -14p. Take half its coefficient (-7). Square it (49) and add it to both sides. Add '49' to each side of the equation. -14p + 49 + p2 = 5 + 49 Reorder the terms: 49 + -14p + p2 = 5 + 49 Combine like terms: 5 + 49 = 54 49 + -14p + p2 = 54 Factor a perfect square on the left side: (p + -7)(p + -7) = 54 Calculate the square root of the right side: 7.348469228 Break this problem into two subproblems by setting (p + -7) equal to 7.348469228 and -7.348469228.Subproblem 1
p + -7 = 7.348469228 Simplifying p + -7 = 7.348469228 Reorder the terms: -7 + p = 7.348469228 Solving -7 + p = 7.348469228 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + p = 7.348469228 + 7 Combine like terms: -7 + 7 = 0 0 + p = 7.348469228 + 7 p = 7.348469228 + 7 Combine like terms: 7.348469228 + 7 = 14.348469228 p = 14.348469228 Simplifying p = 14.348469228Subproblem 2
p + -7 = -7.348469228 Simplifying p + -7 = -7.348469228 Reorder the terms: -7 + p = -7.348469228 Solving -7 + p = -7.348469228 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + p = -7.348469228 + 7 Combine like terms: -7 + 7 = 0 0 + p = -7.348469228 + 7 p = -7.348469228 + 7 Combine like terms: -7.348469228 + 7 = -0.348469228 p = -0.348469228 Simplifying p = -0.348469228Solution
