Question

5x+1/x=6 proved that 25x² +1/x² =26​

Answer 1

Answer:

yes

Step-by-step explanation:

{(5x)+(1/x)}^2= 6^2

25x^2 + 1/x^2 +2.5x.1/x = 36.

25x^2 + 1/x^2 +10 =36

25x^2 +1/x^2= 26

hope it helped you!

Answer 2

5x+1/x=6

5x+1=6x

5x-6x+1=0

-x+1=0

x=1-------------------1/

25x^2+1/x^2= 26--------2/

Substituting 1/ in 2/
