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
\(\frac{-q \pm \sqrt{ p^2 - 4bp}}{2p}\)
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
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)
= \(\frac{-q \pm \sqrt{ q^2 - 4bp}}{2p}\)
