vi. State whether the given equation is a quadratic or
not.
y

+

1

=

3



y



Answer. The equation is
y

+

1

=

3



y



Multiplying the equation with
(y) on both the side.
∴ y(y)

+

y

=

3(y)



y



∴ y^{2}
+ 1 = 3y
∴ y^{2}
– 3 y + 1 = 0
Now it is the standard form
of quadratic equation (i.e.) ax^{2} + bx + c = 0^{ }. Where a
is not equal to zero
and a, b, c are belong to Real
numbers
∴It is a quadratic equation.
