Answer:

This is prime.  (No factors),

Step-by-step explanation:

3x^2 + x + 15.√

This is not possible

Find complex roots using the formula

x = [-1 +/- √1^2 - 4*3*5)] / 6

x = -1/6 +/- √-179) / 6

x = -1 +/- i√179/ 6

So we can write the factors as:

(x - (-1 - i√179/ 6)(x  - (-1 + i√179/ 6)

= (x + 1 + i(√179/ 6)) (x + 1 - i(√179/ 6))

Maybe that is what they want.
