I hope it helps u.

Answer 2

Answer:

Step-by-step explanation:

if the eq is in the form of ax^2+bx+c then the roots are of eq are

-b±√b^2-4ac/2a

the eq is 7x^2+x-1

the roots are -b±√b²-4ac/2a

                =-1±√1-4×7×-1÷2×7

                =-1±√1+28÷14

                =-1±√29/14

               the roots are -1+√29/14 ,-1-√29/14
