Subproblem 1

Set the factor '(-17 + 108p + 60p2)' equal to zero and attempt to solve: Simplifying -17 + 108p + 60p2 = 0 Solving -17 + 108p + 60p2 = 0 Begin completing the square. Divide all terms by 60 the coefficient of the squared term: Divide each side by '60'. -0.2833333333 + 1.8p + p2 = 0.0 Move the constant term to the right: Add '0.2833333333' to each side of the equation. -0.2833333333 + 1.8p + 0.2833333333 + p2 = 0.0 + 0.2833333333 Reorder the terms: -0.2833333333 + 0.2833333333 + 1.8p + p2 = 0.0 + 0.2833333333 Combine like terms: -0.2833333333 + 0.2833333333 = 0.0000000000 0.0000000000 + 1.8p + p2 = 0.0 + 0.2833333333 1.8p + p2 = 0.0 + 0.2833333333 Combine like terms: 0.0 + 0.2833333333 = 0.2833333333 1.8p + p2 = 0.2833333333 The p term is 1.8p. Take half its coefficient (0.9). Square it (0.81) and add it to both sides. Add '0.81' to each side of the equation. 1.8p + 0.81 + p2 = 0.2833333333 + 0.81 Reorder the terms: 0.81 + 1.8p + p2 = 0.2833333333 + 0.81 Combine like terms: 0.2833333333 + 0.81 = 1.0933333333 0.81 + 1.8p + p2 = 1.0933333333 Factor a perfect square on the left side: (p + 0.9)(p + 0.9) = 1.0933333333 Calculate the square root of the right side: 1.045625809 Break this problem into two subproblems by setting (p + 0.9) equal to 1.045625809 and -1.045625809.

Subproblem 1
