Find the roots of the equation 6p2−5p−6=0.6p^2-5p-6=0.6p2−5p−6=0.​​
Question

Find the roots of the equation 6p25p6=0.6p^2-5p-6=0.​​

A.

-2/3  and  3/2

B.

3/4  and  3/2

C.

2/3  and  2/3

D.

-1/3  and  4/3

Correct option is A

Given:​

6p2^2​−5p−6=0.  

Solution:

​​6p2^2−5p−6=0.    

6p2^2−(9-4)p−6=0.    

6p2^2−9p  + 4p −6=0.    

3p(2p -3) + 2(2p - 3) = 0 

(3p + 2) (2p - 3 )  = 0 

then 

(3p + 2)  = 0 

p = 23\frac{-2}{3} 

(2p - 3 ) = 0 

p = 32\frac{3}{2} 

The value of P = 23\frac{-2}{3}  , 32\frac{3}{2}​​
