Question

Factorise : 2x^2+3√5x+5

Answer 1

$2 {x}^{2} + 3 \sqrt{5} x + 5 \\ = 2 {x}^{2} + 2 \sqrt{5} x + \sqrt{5} x + 5 \\ = 2x(x + \sqrt{5} ) + \sqrt{5} (x + \sqrt{5} ) \\ = (2x + \sqrt{5} )(x + \sqrt{5} )$

Answer 2

hey friends ☺

2x² + 3√5x + 5

=> 2x² + 2√5 x+ √5x+5 {< by using splinting method )

=> 2x( x +√5 ) + √5 (x +,√5)

=> (2x +√5)(x+√5) =0

=> x =-√5/2 and x =- √5 Answers ..

hope it helps you !!
