Simplifying p2 + -5p = 21 Reorder the terms: -5p + p2 = 21 Solving -5p + p2 = 21 Solving for variable 'p'. Reorder the terms: -21 + -5p + p2 = 21 + -21 Combine like terms: 21 + -21 = 0 -21 + -5p + p2 = 0 Begin completing the square. Move the constant term to the right: Add '21' to each side of the equation. -21 + -5p + 21 + p2 = 0 + 21 Reorder the terms: -21 + 21 + -5p + p2 = 0 + 21 Combine like terms: -21 + 21 = 0 0 + -5p + p2 = 0 + 21 -5p + p2 = 0 + 21 Combine like terms: 0 + 21 = 21 -5p + p2 = 21 The p term is -5p. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5p + 6.25 + p2 = 21 + 6.25 Reorder the terms: 6.25 + -5p + p2 = 21 + 6.25 Combine like terms: 21 + 6.25 = 27.25 6.25 + -5p + p2 = 27.25 Factor a perfect square on the left side: (p + -2.5)(p + -2.5) = 27.25 Calculate the square root of the right side: 5.220153254 Break this problem into two subproblems by setting (p + -2.5) equal to 5.220153254 and -5.220153254.Subproblem 1
p + -2.5 = 5.220153254 Simplifying p + -2.5 = 5.220153254 Reorder the terms: -2.5 + p = 5.220153254 Solving -2.5 + p = 5.220153254 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + p = 5.220153254 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + p = 5.220153254 + 2.5 p = 5.220153254 + 2.5 Combine like terms: 5.220153254 + 2.5 = 7.720153254 p = 7.720153254 Simplifying p = 7.720153254Subproblem 2
p + -2.5 = -5.220153254 Simplifying p + -2.5 = -5.220153254 Reorder the terms: -2.5 + p = -5.220153254 Solving -2.5 + p = -5.220153254 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + p = -5.220153254 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + p = -5.220153254 + 2.5 p = -5.220153254 + 2.5 Combine like terms: -5.220153254 + 2.5 = -2.720153254 p = -2.720153254 Simplifying p = -2.720153254Solution
The solution to the problem is based on the solutions from the subproblems. p = {7.720153254, -2.720153254}
