Hi there,

Your question is incomplete but I am assuming that from identity 4 you mean this identity:

(x+a) (x+b) = x2 ( square of x) +(a+b)x+ab

Now put a=2, b=3 ,x=5 in this identity

L.H.S  (x+a) (x+b) = (5+2) (5+3)

= (7) (8)

= 56

R.H.S= square of x + (a+b) x + ab

= square of 5 + ( 2+3) 5 + 2×3

=5×5 + (5)5 +6

= 25+25+6

= 50+6

=56

Hence L.H.S = R.H.S

So identity is verified

Hope it helps you

Good luck!
