Answer
$(x-2)(x+15)$.
Work Step by Step
The given polynomial is
$=y^2+13x-30$
Standard form is $x^2+bx+c$.
We have $b=13$ and $c=-30$.
$b$ is positive and $c$ is negative.
Factor pair of $-30$, whose sum is $13$:
$15,-2$
The values of $p$ and $q$ are $-2$ and $15$.
Hence, the factor of the polynomial is $(x+p)(x+q)=(x-2)(x+15)$.
Check:-
$=(x-2)(x+15)$
$=x^2+15x-2x-30$
$=x^2+13x-30$
True.
