Answer:

No solution unless you want to solve for an imaginary number which in that case [tex]a=27i-5[/tex]

Step-by-step explanation:

[tex](a+5)^{2} +36=9[/tex]

[tex](a+5)^2=-27[/tex]

[tex]a+5=\sqrt{-27}[/tex]

Here you can stop and say "no solution" since you cannot square root a negative number, but if you want you can still solve for an imaginary number:

[tex]a+5=\sqrt{-1} \sqrt{27}[/tex]

[tex]a+5=27i[/tex]

[tex]a=27i-5[/tex]
