Q2 of 108 Page 42

Find the root of the following quadratic equations, if they exist, by using the quadratic formula by Shridharacharya Method:


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

ax2 + bx + c = 0


a = 2


b = -2√2


c = 1


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


(-2√2)2 – (4 × 2 × 1)


(4 × 2) - 8


8 – 8


0


Since b2 – 4ac = 0 the roots are real and equal.


Now let us put the values in the above formula






x = 1/√2 , 1/√2
