Question

X2 + y2 – 4x + 10y + 4 = 0. find the center and radius of a circle

Answer 1

Answer:

the center is : (2 , - 5) and radius 5

Step-by-step explanation:

hello :

x² + y² – 4x + 10y + 4 = 0

(x²-4x)+(y²+10y)+4 =0

Completing The Square :

(x²-4x+4)-4+(y²+10y+25)-25+4 =0

(x-2)²+(y+5)²= 5²  .....standard form

the center is : (2 , - 5) and radius 5
