Question

p^3+27/p+3=a and p^3-27/p-3=b then a-b/2

Answer 1

Answer:

$\frac{a - b}{2} = \frac{27}{p} + 3$

Step-by-step explanation:

$a = {p}^{3} + \frac{27}{p} + 3 \\ b = {p}^{3} - \frac{27}{p} - 3 \\a - b = {p}^{3} + \frac{27}{p} + 3 - {p}^{3} + \frac{27}{p} + 3 \\ = 2(\frac{27}{p} + 3) \\ \frac{a - b}{2} = \frac{27}{p} + 3$
