Answer

No Solution

Work Step by Step

Given equation is- $x^{2}+9$ = $0$ Algebraic Solution: $x^{2}$ = $-9$ i.e. $x$ = $\sqrt {-9}$ There is no real number whose square is a negative number. i.e. Equation has no solution Graphical Solution: $x^{2}+9$ = $0$ Now graphing $y$ = $x^{2}+9$ We get no $x-intercept$ i.e. Equation has no real solution.
