Question

3x+2/x=7 ,(9x2-4/x2​

Answer 1

Step-by-step explanation:

3x+2/x-7=0

3x^2+2-7x=0

3x^2-7x+2=0

3x^2-6x-x+2=0

3x(x-2)-1(x-2)=0

(3x-1)(x-2)=0

3x-1=0

x=1/3.......i

x-2=0

x=2.......ii

putting I

9x^2-4/x^2

9×1/9-4/1/9

1-36

-35

putting ii

9×4-4/4

36-1

35

since when we put i we get answer in negative so it is neglected

hence ii will be the ans
