Answer:
and
.
Step-by-step explanation:
Start by adding 1 to both sides of this equation.
.
The square of what number or numbers will lead to the number "1"? It turns out that not only
, but
as well. In other words, the value
can be either 1 or -1. Either way, the equation is still going to hold. That's the reason why there are two solutions to this equation.
Consider the case when
. Add 10 to both sides of the equation.
.
Now, consider the case when
. Again, add 10 to both sides of the equation,
.
Order the two solutions in an increasing order:
,
.
