Question

If a -1/a = 4 find the value of
a²+1/a²
​

Answer 1

Answer:

the answer is 14

surely the answer is coorect

Answer 2

Step-by-step explanation:

first we have to find a.

Therefore, a-1/a = 4

=> 4a = a-1

=> 3a = -1

=> a = -1/3

Now plot the value of a in

a² + 1/a²

= (-1/3)²+1/(-1/3)

= 1/9 + 1/(-1/3)

= (1+9/9)/-1/3

= (10/9)/-1/3

= 10/9 × -3/1

= 10/3 × -1

-10/3 = a
