already factored and easy to find solutions
1.%28x%2B7%29%28x%2B1%29=0.
if x%2B7=0........->.....x=-7...first solution

if x%2B1=0........->.....x=-1...second solution

2.%28x%2B2%29%28x%2B3%29=0
if x%2B2=0........->.....x=-2...first solution

if x%2B3=0........->.....x=-3...second solution

3.x%28x-2%29=0
x=0........->...first solution

if x-2=0........->.....x=2...second solution

4.x%28x-7%29=0
x=0........->...first solution

if x-7=0........->.....x=7...second solution

5.%283x-3%29%284x%2B2%29=0
if 3x-3=0........->.....3x=3..->.....x=1...first solution

if 4x%2B2=0.....->.....4x=-2.->.....x=-1%2F2...second solution
