Solve the following quadratic equations by using Shridharacharya Quadratic Formula:
9x2 – 9(a + b)x + (2a2 + 5ab + 2b2) = 0
When we compare the above quadratic equation with the generalized one we get,
ax2 + bx + c = 0
a = 9
b = – 9(a + b)
c = (2a2 + 5ab + 2b2)
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
⟹ (– 9(a + b)) 2 – (4 × 9 × (2a2 + 5ab + 2b2))
⟹ 81(a2 +2ab + b2) - (36(2a2 + 5ab + 2b2))
⟹ 81a2 +162ab + 81b2 - 72a2 - 180ab - 72b2
⟹ 9a2 - 18ab + 9b2
⟹ 9(a2 - 2ab + b2)
⟹ 32(a – b) 2
Now let us put the values in the above formula
