Answer

$(x+6)(x+1)$.

Work Step by Step

The given polynomial is $=x^2+7x+6$ Standard form is $x^2+bx+c$. We have $b=7$ and $c=6$. The value of $c$ is positive. Factor pair of $6$, whose sum is $7$: $6,1$ The values of $p$ and $q$ are $6$ and $1$. Hence, the factor of the polynomial is $(x+p)(x+q)=(x+6)(x+1)$. Check:- $=(x+6)(x+1)$ $=x^2+x+6x+6$ $=x^2+7x+6$ True.
