Answer 2

Answer:

heya!!!

Aashi this Syd the answer for ur question is as follows.............

Step-by-step explanation:

(2x-y+3)(2x-y-3)

step 1-

from the identity of (a²-b²) =(a+b)(a-b)

we know that here (2x-y) is a and 3 is considered as b where as in (2x-y-3) (2x-y) is a and -3 is b

step 2-

(2x-y)²-(3)² it can also be concluded as the answer here.

step 3-

(2x-y)²=from a²+b²-l2ab

4x²+y²-4xy

step 4-

4x²+y²-4xy-9 Answer.

hope it helps.
