(x+9)(x+4). After some practice of factoring integers, you'll be able to do problems like these in your head. However not all polynomials are easily factorable.

The surefire way is to find the roots using the quadratic formula. If the roots are r%5B1%5D and r%5B2%5D, then the polynomial in factored form is %28x+-+r%5B1%5D%29%28x+-+r%5B2%5D%29.
