2x^2 + 2y^2 -x +y -3=0 is n equation of a circle Find (a) the coordinate of its centre (b)the radius of the circle (c)the equations of (i)tangent (ii)normal to the circle at point (1 , 2)

i'm sorry i don't know

step-by-step explanation:

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
