Step-by-step explanation:
A proportion can be called as an equation to check two ratios are equal to each other or not.
Whenever the terms of a proportion are cross multiplied, the cross products will always be equal.

Answer:
(<u>fg)(x) = 12x³ + 12x²</u>
Step-by-step explanation:
Given f(x) = 3x + 6 and g(x) = 2x²
To find (fg)(x), we multiply g(x) with f(x)
(fg)(x)
(3x + 6) *( 2x²)
(3x) ( 2x²) + 6*2x²
6x³ + 12x²
hence (<u>fg)(x) = 6x³ + 12x²</u>
