Question

if b squre2 - 4 ac=32 then the roots of quadratic equations are ?​

Answer 1

Correct option is

D

−  

2a

b

​

±  

2a

b  

2

−4ac

​

 

​

 

If b  

2

−4ac≥0

Then the roots are real.

Hence

By using quadratic formula, we get the roots as

2a

−b±  

b  

2

−4ac

​

 

​

 

Hence, option 'D' is correct
