Question

a/3+3/a=-1 find a⁵-26a²+3a+14​

Answer 1

Step-by-step explanation:

let a/3 = x

so 3/a = 1/x

a/3+3/a=-1

x + 1/x = -1

x² + 1 = -x

x² + x + 1 = 0

x³- 1³ = (x- 1) (x²+ x+ 1)

x³- 1 = (x- 1) × 0

x³- 1 = 0

x³= 1

a³/27 = 1

a³ = 27

a = 3

put the value of a in a⁵-26a²+3a+14

and get your answer.
