We need an equation for this, theres no 'formula' for doing this (ignoring the quadratic formula, as that is a long-winded way of factorising a quadratic equation)
Let

. Then

, and so as

, you have

. The limit is then equivalent to
The statements which are correct about the equation of circle
are 1) The radius of the circle is 3 units,2) The center of the circle lies on the x axis,5) The radius of this circle is the same the radius of the circle whose equation is
.
Given the equation of circle be
.
We are required to find the appropriate statements related to the equation
.
can be written as under:


-9=0


Equation of a circle usually in the form
in which a is radius.
From the comparison of both the equations we get that radius is 3 units.
From the equation point will be (1,0). It is on the x axis.
Hence the statements which are correct about the equation of circle
are 1) The radius of the circle is 3 units,2) The center of the circle lies on the x axis,5) The radius of this circle is the same the radius of the circle whose equation is
.
