Answer 2

Answer:

16x² is the crt answer

Step-by-step explanation:

Let p should be added to to make x* + 64 perfect square.

24 +64 +p= (m + n)²

(22)2 + 82 +p=m² + n2 +2mn

/* Compare bothsides of the equation, we get*/

m = 2, n = 8 p=2mn

= p = 2×x² x 8

16.22

Therefore,

16x2 should be added to make

x +64 perfect square.
