Subproblem 1

Set the factor 'p' equal to zero and attempt to solve: Simplifying p = 0 Solving p = 0 Move all terms containing p to the left, all other terms to the right. Simplifying p = 0

Subproblem 2

Set the factor '(-6 + -5p + 2p2)' equal to zero and attempt to solve: Simplifying -6 + -5p + 2p2 = 0 Solving -6 + -5p + 2p2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -3 + -2.5p + p2 = 0 Move the constant term to the right: Add '3' to each side of the equation. -3 + -2.5p + 3 + p2 = 0 + 3 Reorder the terms: -3 + 3 + -2.5p + p2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -2.5p + p2 = 0 + 3 -2.5p + p2 = 0 + 3 Combine like terms: 0 + 3 = 3 -2.5p + p2 = 3 The p term is -2.5p. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5p + 1.5625 + p2 = 3 + 1.5625 Reorder the terms: 1.5625 + -2.5p + p2 = 3 + 1.5625 Combine like terms: 3 + 1.5625 = 4.5625 1.5625 + -2.5p + p2 = 4.5625 Factor a perfect square on the left side: (p + -1.25)(p + -1.25) = 4.5625 Calculate the square root of the right side: 2.136000936 Break this problem into two subproblems by setting (p + -1.25) equal to 2.136000936 and -2.136000936.

Subproblem 1

p + -1.25 = 2.136000936 Simplifying p + -1.25 = 2.136000936 Reorder the terms: -1.25 + p = 2.136000936 Solving -1.25 + p = 2.136000936 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + p = 2.136000936 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + p = 2.136000936 + 1.25 p = 2.136000936 + 1.25 Combine like terms: 2.136000936 + 1.25 = 3.386000936 p = 3.386000936 Simplifying p = 3.386000936

Subproblem 2

p + -1.25 = -2.136000936 Simplifying p + -1.25 = -2.136000936 Reorder the terms: -1.25 + p = -2.136000936 Solving -1.25 + p = -2.136000936 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + p = -2.136000936 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + p = -2.136000936 + 1.25 p = -2.136000936 + 1.25 Combine like terms: -2.136000936 + 1.25 = -0.886000936 p = -0.886000936 Simplifying p = -0.886000936
