Question

( m+3)( m-3) solve with suitable identity​

Answer 1

Answer:

m² - 9

Step-by-step explanation:

(m + 3) (m - 3)

= m × m - 3 × m + 3 × m - 3 × 3

= m² - 3m + 3m - 9

= m² - 9 ans.

Answer 2

solution:-

$\implies \: (m + 3)(m - 3)$

we know that formula of

→(a+b)(a-b)=a^2-b^2

where

a=m

and b=3

m^2-3^2

m^2-9
