Question

x^2-3x-28/x^2-49=3/17,x is not equalto +-7

Answer 1

Answer:

(x^2-3x-28)/x^2-49=3/17 ;x is not equal to+-7

:  (x^2-7x+4x-28) / (x+7)(x-7)=3/17

:  {x(x-7)+4(x-7)} / (x+7)(x-7)=3/17

:  {(x-7)(x+4)} / (x+7)(x-7)=3/17

:  x+4/(x+7)=3/17

:  17x+68=3x+21

:  17x-3x=21-68

:  14x=(-47)

:  x=(-47)/14
