Question

factorise 7xsquare +2 root 14 x +2

Answer 1

$= > 7 {x}^{2} + 2 \sqrt{14} x + 2 \\ \\ = > 7 {x}^{2} + \sqrt{14} x + \sqrt{14} x + 2 \\ \\ = > \sqrt{7} x( \sqrt{7} x + \sqrt{2} ) + \sqrt{2} ( \sqrt{7} x + \sqrt{2} ) \\ \\ = > ( \sqrt{7} x + \sqrt{2} )( \sqrt{7} x + \sqrt{2} ) \\ \\ = > { ( \sqrt{7} x + \sqrt{2} )}^{2}$

Answer 2

Hey dear !!


Here is yr answer....


=> 7x²+2√14x+2

=> 7x²+√14x+√14x+2

=> √7x(√7x+√2) + √2(√7x+√2)

=> (√7x+√2)(√7x+√2)

=> (√7x+√2)²



Hope it hlpz....
