y q
1
the value of a​

Answer 1

Step-by-step explanation:

the value of x is (a) 3

hope it helps

Answer 2

Answer:

Correct option is

C

3,2

As we know that if the equation ax

2

+by

2

+2hxy+2gx+2fy+c=0 represents a circle then-

coefficient of x

2

=Coefficient of y

2

, i.e., a=b

Coefficient of xy=0, i.e., h=0

Now if the equation px

2

+(2−q)xy+3y

2

−6qx+30y+6q=0 represents the equation of circle then-

Coefficient of x

2

=Coefficient of y

2

⇒p=3

Coefficient of xy=0

2−q=0⇒q=2

Hence if the equation px

2

+(2−q)xy+3y

2

−6qx+30y+6q=0 represents a circle then the value of p and q are 3 and 2 respectively.
