Question

the centre of the circle X2 +y2+8x+10y-8=0​

Answer 1

Answer:

Step-by-step explanation:

Given Equation can be Converted to Standard Equation of Circle as follows

(x  

2

+8x+16)+(y  

2

+10y+25)=8+25+16

⇒(x+4)  

2

+(y+5)  

2

=7  

2

..........(1)

and Standard equation of Circle is : (x+f)  

2

+(y+g)  

2

=r  

2

.........(2)

where, r = radius of Circle

           (−f,−g) is the center

Comparing (1) and (2)

center:(−4,−5)

radius:7
