Answer
No solution
Work Step by Step
Solve algebraically:
$x^2+9=0$ (Substract with 9)
$x^2=-9$
Since $x^2$ must be non-negative, the equation has no solution.
Solve graphically:
We sketch the graph of $y=x^2+9$ as shown below.
We can see that the graph does not intercept the x-axis at any point.
So, the equation has no solution.
