Answer
This equation has exactly one real solution.
Work Step by Step
$x^{2}+2.20x+1.21=0$
The formula for the discriminant is $D=b^{2}-4ac$. For this equation, $a=1$, $b=2.20$ and $c=1.21$.
Substitute the known values in the formula:
$D=2.20^{2}-4(1)(1.21)=4.84-4.84=0$
Since $D=0$, this equation has exactly one real solution.
