#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#
