Question

(2m+3/5)(2m-3/5) expand by suitable identity

Answer 1

Answer:

it is in the form of a^2-b^2

Step-by-step explanation:

(2m)^2-(3/5)^2

Answer 2

Answer:

(2m+3/5)(2m-3/5)=

by identity (a+b)(a-b)=a^2-b^2

=>(2m)^2 - (3/5)^2\

=>4 m^2 - 9/25

=>(100 m^2 - 9)/25

The final ans is

100 m^2 -9

25
