Subtract :- 22/x from x+1 / x -1 =?2X Means x raise to 2

Answer»

Step-by-step EXPLANATION:

geometric mean ⇒ (√((x^2 +2).2)) = 6−3x

the EQUATION valid for 6−3x ≥0

or x ≤ 2.

squaring both SIDES gives

2x^2 +4 = 9x^2 −36x+36

7x^2 −36x+32 = 0

(7x−8)(x−4)=0

{ ((x=(8/7)←accept)),((x=4 ←rejected)) :}

the value of x is (8/7).

please follow me...

thanks my answer
