Step-by-step explanation:

I assume this means multiplication of functions, and not "f of g of x".

when applying a basic mathematical operation on functions, we are doing this with their expressions.

(f×g)(x) = (x² + 12x + 35) × (x + 7) =

= x³ + 7x² + 12x² + 84x + 35x + 245 =

= x³ + 19x² + 119x + 245
