Given the rational function
f
(
x
)
=
x
2
−
3
x
−
28
x
2
−
8
x
+
7
\displaystyle {f{{\left({x}\right)}}}=\frac{{{x}^{{2}}-{3}{x}-{28}}}{{{x}^{{2}}-{8}{x}+{7}}}
f
(
x
)
=
x
2
−
8
x
+
7
x
2
−
3
x
−
28
find any hole(s) of the function.
x
=
1
\displaystyle {x}={1}
x
=
1
x
=
−
4
\displaystyle {x}=-{4}
x
=
−
4
x
=
7
,
x
=
−
4
\displaystyle {x}={7},\ {x}=-{4}
x
=
7
,
x
=
−
4
x
=
7
\displaystyle {x}={7}
x
=
7
x
=
7
,
x
=
1
\displaystyle {x}={7},\ {x}={1}
x
=
7
