Question

factorise it for me

Answer 1

Hey !!!

7x² + 2√14x + 2

Using spliting method of quadratic polynomial

7x² + √14x + √14x + 2 >[°•° √14 + √14 = 2√14]

√7x ( √7x + √2 ) + √2 ( √7x + √2 )

(√7x + √2 ) ( √7x + √2 )
$\bf{taking \: common}$

we know that ,

( a + b ) ( a + b ) = (a + b)²
using this identity

since, (√7x + √2 )²
$\bf{answer}$

7x^2+√14x+√14x+2
√7x(√7x+√2)+√2(√7x+√2)
(√7x+√2)(√7x+√2)
or
