Question

Simplify (3-√11)(3+√11)​

Answer 1

Simplify

(3-√11)(3+√11)

Solution!

• It is in The Form of (a-b) (a+b)

So,

$\boxed{\sf{a² - b²}}$

a = 3 , b = √11

Now, putting the values Of a and b

a² - b²

⟹(3)² - (√11)²

⟹9 - 11

⟹-3

$\boxed{\sf{Ans = - 3}}$

Answer 2

$\bf\green{\underline{\underline{Given:-}}}$

Simplify (3-√11)(3+√11)

$\bf\green{\underline{\underline{Formula\: used:-}}}$

$\pink{\fbox{(a+b)(a-b) = (a²-b²)}}$

$\bf\green{\underline{\underline{Solution:-}}}$

a = 3

b = √11

(3-√11)(3+√11)

=> (a - b)(a + b)

=> (a²-b²)

=> (3)² - (√11)²

=> 9 - 11

=> -2$\:\:\:\:\:\:$Ans.
