Simplifying 8p2 + 7 = 16p Reorder the terms: 7 + 8p2 = 16p Solving 7 + 8p2 = 16p Solving for variable 'p'. Reorder the terms: 7 + -16p + 8p2 = 16p + -16p Combine like terms: 16p + -16p = 0 7 + -16p + 8p2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.875 + -2p + p2 = 0 Move the constant term to the right: Add '-0.875' to each side of the equation. 0.875 + -2p + -0.875 + p2 = 0 + -0.875 Reorder the terms: 0.875 + -0.875 + -2p + p2 = 0 + -0.875 Combine like terms: 0.875 + -0.875 = 0.000 0.000 + -2p + p2 = 0 + -0.875 -2p + p2 = 0 + -0.875 Combine like terms: 0 + -0.875 = -0.875 -2p + p2 = -0.875 The p term is -2p. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2p + 1 + p2 = -0.875 + 1 Reorder the terms: 1 + -2p + p2 = -0.875 + 1 Combine like terms: -0.875 + 1 = 0.125 1 + -2p + p2 = 0.125 Factor a perfect square on the left side: (p + -1)(p + -1) = 0.125 Calculate the square root of the right side: 0.353553391 Break this problem into two subproblems by setting (p + -1) equal to 0.353553391 and -0.353553391.Subproblem 1
p + -1 = 0.353553391 Simplifying p + -1 = 0.353553391 Reorder the terms: -1 + p = 0.353553391 Solving -1 + p = 0.353553391 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + p = 0.353553391 + 1 Combine like terms: -1 + 1 = 0 0 + p = 0.353553391 + 1 p = 0.353553391 + 1 Combine like terms: 0.353553391 + 1 = 1.353553391 p = 1.353553391 Simplifying p = 1.353553391Subproblem 2
p + -1 = -0.353553391 Simplifying p + -1 = -0.353553391 Reorder the terms: -1 + p = -0.353553391 Solving -1 + p = -0.353553391 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + p = -0.353553391 + 1 Combine like terms: -1 + 1 = 0 0 + p = -0.353553391 + 1 p = -0.353553391 + 1 Combine like terms: -0.353553391 + 1 = 0.646446609 p = 0.646446609 Simplifying p = 0.646446609Solution
