Question

obtain the quadratic equation if root of 2 and 5​

Answer 1

Answer:

Correct option is

B

x  

2

−4x−1=0

One root of the equation is 2+  

5

​  

. So, the next root will be 2−  

5

​  

 

∴ x=2+  

5

​  

 and x=2−  

5

​  

 

∴ (x−(2+  

5

​  

))(x−(2−  

5

​  

))=0

∴ (x  

2

+(4−5)−2x−  

5

​  

x−2x+  

5

​  

x)=0

∴ x  

2

−4x−1=0 is the required quadratic equation.
