Question

Factors of 4 - m^2 are____​

Answer 1

Question:

Factorise :

4 - m²

Answer:

we know,

$(a+b)(a-b) = a² - b²$

so,

$4 - m²$

= $(2)² - (m)²$

= $(2+m)(2-m)$

Answer 2

4 - m²

4 can be written as 2²

So , 2² - m²

Using the identity

• a² - b² = ( a + b ) ( a - b )

( 2 + m ) ( 2 - m )
