Math FOIL Help!?

Well earlier I got help! Thanks. But I got stuck with these 4 questions that my teacher gave me! Please help me! I have to answer them in FOIL! She gave us the equation but we have to put it back in Foil! Even helping with one would help alot!

1. x^2+11x+3

2. x^2+4x+11

3. 2x^2+5x+2

4. 3x^2+x-2

I need to put them in the FOIL form like (x+2)(x-3)!

Please help me! Thanks!

3.

(2x + 1)(x + 2).

4.

(3x – 2)(x + 1).

1 & 2 cannot be factorised by inspection. No. 1 needs use of the quadratic formula, and no. 2 when equated to 0 has complex roots.
