Question

(2.5l-0.5m) (2.5l+0.5m) please help to solve it faster

Answer 1

Answer:

6.25l^2 - 0.25m^2 is the result .

Step-by-step explanation:

Given equation : ( 2.5l - 0.5m )( 2.5l + 0.5m )

On observing both the terms, we get the given equation is in the form of ( a + b )( a - b ),

From the identities of factorization,

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

∴ ( 2.5l )^2 - ( 0.5m )^2

⇒ ( 2.5 l x 2.5 l ) - ( 0.5 m - 0.5 m )

⇒ 6.25 l^2 - 0.25 m^2

Hence, the value of ( 2.5l - 0.5m ) ( 2.5l + 0.5m ) is 6.25l^2 - 0.25m^2
