Find the root of

Answer :

When we compare the above quadratic equation with the generalized one we get,

ax2 + bx + c = 0


a = 1


b = 4


c = 5


There is one formula developed by Shridharacharya to determine the roots of a quadratic equation which is as follows:



Before putting the values in the formula let us check the nature of roots by b2 – 4ac >0


(4)2 – (4 × 1 × 5)


16 – 20


-4


Since b2 – 4ac = -4 the roots are imaginary.


Therefore the given quadratic equation does not has real roots.
