Question

Question : If x = 3 and y = -1, find the values of each of the following using in identity:

(3/x – x/3)(x​2 /9 + 9/x​2 + 1)​

Answer 1

Answer:

(3/3 -3/3) (6/9+9/6+1)

= 0× 57/18

=0

Answer 2

Step-by-step explanation:

(3/x - x/3)(x2/9 + 9/x2 + 1)

= (3/3 - 3/3) (3^2/9 + 9/3^2 + 1)

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

= 0 * (1 + 1 + 1)

= 0
