Question

Find the values of a, b if ax² + bxy+3y² – 5x +2y-3= 0 represents a circle also find radius
and centre of the circle.in which chapter is this
​

Answer 1

Answer:

hey mate !! here is your answer...

Step-by-step explanation:

Here the circle equation is ax^2+2hxy+3y^2–6x-12y-12=0 the circle equation is x^2+y^2+2gx+2fy+c=0 when we compare and see the

x^2 coefficient=y^2 coefficient ……(1)

So now the x squre coefficient=a then y square coefficient=3 then from

Equation 1

a=3
