Question

evalute by using identities

Answer 1

$\bold{Answer :}$

Identity rule :

a² - b² = (a + b) (a - b)

$\bold{(1)}$

Now, 93² - 107²

= (93 + 107) (93 - 107)

= 200 (- 14)

= - 2800

$\bold{(2)}$

Now, 60² - 63²

= (60 + 63) (60 - 63)

= 123 (- 3)

= - 369

Answer 2

Answer:

Identity rule :

a² - b² = (a + b) (a - b)

\bold{(1)}

Now, 93² - 107²

= (93 + 107) (93 - 107)

= 200 (- 14)

= - 2800

\bold{(2)}

Now, 60² - 63²

= (60 + 63) (60 - 63)

= 123 (- 3)

= - 36
