Simplifying -5p2 = -16p + -3 Reorder the terms: -5p2 = -3 + -16p Solving -5p2 = -3 + -16p Solving for variable 'p'. Reorder the terms: 3 + 16p + -5p2 = -3 + -16p + 3 + 16p Reorder the terms: 3 + 16p + -5p2 = -3 + 3 + -16p + 16p Combine like terms: -3 + 3 = 0 3 + 16p + -5p2 = 0 + -16p + 16p 3 + 16p + -5p2 = -16p + 16p Combine like terms: -16p + 16p = 0 3 + 16p + -5p2 = 0 Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. -0.6 + -3.2p + p2 = 0 Move the constant term to the right: Add '0.6' to each side of the equation. -0.6 + -3.2p + 0.6 + p2 = 0 + 0.6 Reorder the terms: -0.6 + 0.6 + -3.2p + p2 = 0 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + -3.2p + p2 = 0 + 0.6 -3.2p + p2 = 0 + 0.6 Combine like terms: 0 + 0.6 = 0.6 -3.2p + p2 = 0.6 The p term is -3.2p. Take half its coefficient (-1.6). Square it (2.56) and add it to both sides. Add '2.56' to each side of the equation. -3.2p + 2.56 + p2 = 0.6 + 2.56 Reorder the terms: 2.56 + -3.2p + p2 = 0.6 + 2.56 Combine like terms: 0.6 + 2.56 = 3.16 2.56 + -3.2p + p2 = 3.16 Factor a perfect square on the left side: (p + -1.6)(p + -1.6) = 3.16 Calculate the square root of the right side: 1.777638883 Break this problem into two subproblems by setting (p + -1.6) equal to 1.777638883 and -1.777638883.Subproblem 1
p + -1.6 = 1.777638883 Simplifying p + -1.6 = 1.777638883 Reorder the terms: -1.6 + p = 1.777638883 Solving -1.6 + p = 1.777638883 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '1.6' to each side of the equation. -1.6 + 1.6 + p = 1.777638883 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + p = 1.777638883 + 1.6 p = 1.777638883 + 1.6 Combine like terms: 1.777638883 + 1.6 = 3.377638883 p = 3.377638883 Simplifying p = 3.377638883Subproblem 2
p + -1.6 = -1.777638883 Simplifying p + -1.6 = -1.777638883 Reorder the terms: -1.6 + p = -1.777638883 Solving -1.6 + p = -1.777638883 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '1.6' to each side of the equation. -1.6 + 1.6 + p = -1.777638883 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + p = -1.777638883 + 1.6 p = -1.777638883 + 1.6 Combine like terms: -1.777638883 + 1.6 = -0.177638883 p = -0.177638883 Simplifying p = -0.177638883Solution
