Question

(a3+3a²+3a +5) =(3+5)

plz help! thx so much!​

Answer 1

Given that

• a³+3a²+9a = 1           ...(1)
• a(a²+3a+9) = 1
• So 1/a = a²+3a+9
• ⇒ 3/a = 3a²+9a+27       ...(2)
• Hence value of

a³+3/a = a³+3a²+9a+27         [ using (1) ]

• a³+3/a = 1+27                         [ using (2) ]
• a³+3/a = 28
