Answer 1

sanyam purchased more by 36

Answer 2

Answer:

Sanyam purchased games CD more than Gautam and by 36 CD's

Step-by-step explanation:

Number of games CD purchased by Gautam : x² + 8x - 20

Number of games CD purchased by Sanyam : (x + 4)²

Since, number of games CD is a positive quantity. So, to find who purchased more games CD we can take any positive value of x

Let us take x = 2

Then number of games CD purchased by Gautam = 0

And number of games CD purchased by Sanyam = 36

Therefore, Sanyam purchased games CD more than Gautam and by 36 - 0 = 36 CD's
