Simplifying -2p2 + 20p + 34 = 0 Reorder the terms: 34 + 20p + -2p2 = 0 Solving 34 + 20p + -2p2 = 0 Solving for variable 'p'. Factor out the Greatest Common Factor (GCF), '2'. 2(17 + 10p + -1p2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(17 + 10p + -1p2)' equal to zero and attempt to solve: Simplifying 17 + 10p + -1p2 = 0 Solving 17 + 10p + -1p2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -17 + -10p + p2 = 0 Move the constant term to the right: Add '17' to each side of the equation. -17 + -10p + 17 + p2 = 0 + 17 Reorder the terms: -17 + 17 + -10p + p2 = 0 + 17 Combine like terms: -17 + 17 = 0 0 + -10p + p2 = 0 + 17 -10p + p2 = 0 + 17 Combine like terms: 0 + 17 = 17 -10p + p2 = 17 The p term is -10p. Take half its coefficient (-5). Square it (25) and add it to both sides. Add '25' to each side of the equation. -10p + 25 + p2 = 17 + 25 Reorder the terms: 25 + -10p + p2 = 17 + 25 Combine like terms: 17 + 25 = 42 25 + -10p + p2 = 42 Factor a perfect square on the left side: (p + -5)(p + -5) = 42 Calculate the square root of the right side: 6.480740698 Break this problem into two subproblems by setting (p + -5) equal to 6.480740698 and -6.480740698.Subproblem 1
p + -5 = 6.480740698 Simplifying p + -5 = 6.480740698 Reorder the terms: -5 + p = 6.480740698 Solving -5 + p = 6.480740698 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + p = 6.480740698 + 5 Combine like terms: -5 + 5 = 0 0 + p = 6.480740698 + 5 p = 6.480740698 + 5 Combine like terms: 6.480740698 + 5 = 11.480740698 p = 11.480740698 Simplifying p = 11.480740698Subproblem 2
p + -5 = -6.480740698 Simplifying p + -5 = -6.480740698 Reorder the terms: -5 + p = -6.480740698 Solving -5 + p = -6.480740698 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + p = -6.480740698 + 5 Combine like terms: -5 + 5 = 0 0 + p = -6.480740698 + 5 p = -6.480740698 + 5 Combine like terms: -6.480740698 + 5 = -1.480740698 p = -1.480740698 Simplifying p = -1.480740698Solution
