Factorise :-
2x3 + 9x2 + 10x + 3
Answer :
Factorise : 2 x3 + 9 x 2 + 10 x + 3 , So
2 x3 + 2 x 2 + 7 x 2 + 3 x + 7 x + 3
2 x3 + 7 x 2 + 3 x + 2 x 2 + 7 x + 3
x ( 2 x 2 + 7 x + 3 ) + 1 ( 2 x 2 + 7 x + 3 )
( x + 1 ) ( 2 x 2 + 7 x + 3 )
( x + 1 ) [ 2 x 2 + 6 x + x + 3 ]
( x + 1 ) [ 2 x ( x + 3 ) + 1 ( x + 3 ) ]
( x + 1 ) ( 2 x + 1 ) ( x + 3 ) ( Ans )
