The solution of the quadratic equation bx2 + cx + a = 0 is given by

A.
x = b (pm) (frac{sqrt{b^2 – 4ac}}{2a}) 
B.
x = c (pm) (frac{sqrt{b^2 – 4ab}}{2b}) 
C.
x = c (pm) (frac{sqrt{c^2 – 4ab}}{2b}) 
D.
x = b (pm) (frac{sqrt{b^2 – 4ac}}{2b})
Correct Answer: Option C
Explanation
bx2 + cx + a = 0
a = b; b = c; c = a
x = b (pm) (frac{sqrt{b^2 – 4ac}}{2a})
x = c (pm) (frac{sqrt{c^2 – 4ab}}{2b})
