Answer:
[tex](x+3)^2 + y^2 =25[/tex]
Step-by-step explanation:
The general equation of a circle has the form:
[tex](x-h)^2 + (y-k)^2 =r^2[/tex]
Where the point (h, k) is the center of the circle and r is the radius
In this case the center is (-3, 0) and the radius is [tex]r=5[/tex]
So [tex]h=-3\\k=0[/tex]
Finally the equation of the circle is:
[tex](x-(-3))^2 + (y-0)^2 =5^2[/tex]
[tex](x+3)^2 + y^2 =25[/tex]
