Explanation:
You can always combine like terms, before or after any application of the distributive property.
x(3 +4) = 3x +4x = 7x . . . . . terms combined after distributing x
(x +1)(x +2) = x^2 +1x +2x +1 = x^2 +3x +1 . . . . . terms combined after using the distributive property
x(3 +4x) = 3x +4x^2 . . . . . . terms cannot be combined (unlike terms)
