Question

Find the distance between the centres of
the circles
$x {}^{2} + y {}^{2}$
+ 8x + 10y - 2 = 0 and
x² + y² + 2x+2y-1 = 0.​

Answer 1

Answer:

Answer will be 5

Step-by-step explanation:

As you know standard eq of the circle is

x^2+y^2+2gx+2fy+c=0

And the coordinate of the centre is (-g, -f)

So our coordinates will be (-4,-5) & (-1,-1)

Then use the distance formula

Got it.....
