plz mark me as the brainlist

Answer 2

• Given - 1 - 64 ( a- 2b)^2

• To do - Factorisation

• Solution -

- 64 ( a- 2b)^2

- 64 ( a- 2b ) ( a- 2b)

-64 ( a- 2b) ( a- 2b)

(-8)(8) ( a- 2b) (a -2b)

ADDITIONAL INFORMATION

---------------------------------------------

Some more Identity

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

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

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

(x+ a )(X+ b) = x^2 + (a + b) X + ab
