Is the following factor in factor form, completely expanded form or in partially expanded form?
$$(x+2)(x-1)+7(x+1)$$.

Given factor: $$(x+2)(x-1)+7(x+1)$$.
Since, In $$(x+2)(x-1)+7(x+1)$$, terms $$(x+2)$$ and $$(x-1)$$ are in product with each other and are in parenthesis and term $$7(x+1)$$ is in addition to the result of product of $$(x+2)$$ and $$(x-1)$$.
$$\therefore (x+2)(x-1)+7(x+1)$$ is in partially expanded form.
