Question

Factorize 7x^2 +2V14 x + 2
Note- V is root​

Answer 1

Answer:

Heya!

◆ METHOD 1 (By splitting mid term)

7x² + 2√14x + 2

=> 7x² + √14x + √14x + 2

=> √7x(√7x + √2) + √2(√7x + √2)

=> (√7x + √2)(√7x + √2)

=> (√7x+ √2)²

◆ METHOD 2 (By using identity)

Using identity : - (a + b)² = a² + 2ab + b²

7x² + 2√14x + 2

=> (√7x)² + 2 × (√7x) × (√2) + (√2)²

=> (√7x + √2)²
