write answer in simplest form.

Answer 1

factor everything first so you can get rid of terms can you do this?

Answer 2

?

Answer 3

\[=((x ^{2}+2x-15)(7x-14))/((x ^{2}+4x-5)(x ^{2}-4))\]
\[=((x+5)(x-3)\times7(x-2))/((x+5)(x-1)\times(x-2)(x+2))\]
when\[ x \neq -5\]
\[x \neq 2\]
\[=7(x-3)/(x ^{2}+x-2)\]
