Question

$2x {}^{3} + 3 \sqrt{5x} + 5$

Answer 1

Heya !!



2X² + 3√5 X + 5




=> 2X² + √5X + 2√5X + 5



=> X ( 2X + √5 ) + √5 ( 2X + √5 )




=> ( 2X + √5 ) ( X + √5 ) = 0





=> ( 2X + √5 ) = 0 Or ( X + √5 ) = 0




=> X = -√5/2 or X = -√5

Answer 2

$\textbf{Hello user !! }$

__________________________________________

2 x^2 + 3 √5 x + 5 = 0

2 x ^2 + √ 5 x + 2 √ 5 x + 5 = 0

Taking commons !

x ( 2 x + √ 5 ) + √ 5 ( 2 x + √ 5 ) = 0

( 2 x + √ 5 ) or ( x + √ 5 ) = 0

2 x + √ 5 = 0 , x + √ 5 = 0

2 x = - √ 5 , x = - √ 5

x = - √ 5 / 2 , x = - √ 5
