The solution of the quadratic equation px2 + qx + b = 0 is
-
A.
(sqrt{frac{-b pm b^2 – 4ac}{2a}}) -
B.
(frac{-b pm sqrt{ p^2 – 4pb}}{2a}) -
C.
(frac{-q pm sqrt{ q^2 – 4bp}}{2p}) -
D.
(frac{-q pm sqrt{ p^2 – 4bp}}{2p})
Correct Answer: Option C
Explanation
px2 + qx + b = 0
Using almighty formula
(frac{-b pm sqrt{ b^2 – 4ac}}{2a})………(i)
Where a = p, b = q and c = b
substitute for this value in equation (i)
= (frac{-q pm sqrt{ q^2 – 4bp}}{2p})
