Answer:

Factors are  ( 3x - 1 ) ( x + 1).

To find : Factor.

Solution : We have given that  3x²+ 2x - 1.

By factoring :    3x²+ 3x -1x - 1.

Taking common 3x in first two terms and -1 from last two terms .

   3x( x + 1) -1 (x + 1 ).

On grouping :    ( 3x - 1 ) ( x + 1).

Therefore , Factors are  ( 3x - 1 ) ( x + 1).

jason wants to choose 9 players for his track team ,there are 12 players to choose from.how many different teams can jason make?
mote1985 [20]
He could only make one team, considering that if you do 12-9, you are left with 3, and Jason wants to have his team consisted of 9 players. However, if you make 3 teams with 4 players on each team, or 4 teams with 3 players on each team, you could do that as well.
