Question

Using identities, evaluate :-107x93​

Answer 1

By using the identity,

$(a + b) \: \: (a - b)\: = \: a {}^{2} - b {}^{2}$

Now,

(100+7)(100-7) = 100^2 - 7^2

=10000 -49

=9951......ans

Answer 2

With the help of (a+b) (a-b) = a^2- b^2

(100+7)(100-7)

= 100^2 - 7^2

= 10000-49

=9951 Ans.

Thank you

I hope I made you understand
