x^3+12x^2+47x+60

Explanation:

The polynomial you posted is called a cubic function. The standard form for this function is:
a^3 + bx^2 + cx + d where a \ne 0

Therefore you can just expand the polynomial expression you posted like this:

(x+3)(x+4)(x+5)

= (x+3)(x^2 + 9x + 20)

= x^3+12x^2+47x+60
