x%5E2%2B5x%2B5=x%2B1

This has an x%5E2 term in it so it must be done by
getting a 0 on the right side by adding -x-1 to both sides:

x%5E2%2B4x%2B4=0

Then we factor the left side:

%28x%2B2%29%28x%2B2%29=0

Use the zero-factor property

x%2B2=0 gives solution x=-2

x%2B2=0 gives solution x=-2

So both solutions are the same. So there
is just one solution  x=-2
