Answer 2

1. Answer:
2. Let p (x) = x + 1 / x = 2
4. Let p (x) = x + 1 / x = 2= x + 1 = 2x
6. Let p (x) = x + 1 / x = 2= x + 1 = 2x= 2x - x = 1
8. Let p (x) = x + 1 / x = 2= x + 1 = 2x= 2x - x = 1or, x = 1.
10. Let p (x) = x + 1 / x = 2= x + 1 = 2x= 2x - x = 1or, x = 1.let g(x) = x^3 + 1/x^3
12. Let p (x) = x + 1 / x = 2= x + 1 = 2x= 2x - x = 1or, x = 1.let g(x) = x^3 + 1/x^3since, x = 1
14. Let p (x) = x + 1 / x = 2= x + 1 = 2x= 2x - x = 1or, x = 1.let g(x) = x^3 + 1/x^3since, x = 1therefore,
16. Let p (x) = x + 1 / x = 2= x + 1 = 2x= 2x - x = 1or, x = 1.let g(x) = x^3 + 1/x^3since, x = 1therefore,g (1) = (1)^3 +1 / (1)^3
18. Let p (x) = x + 1 / x = 2= x + 1 = 2x= 2x - x = 1or, x = 1.let g(x) = x^3 + 1/x^3since, x = 1therefore,g (1) = (1)^3 +1 / (1)^3= 1 + 1 / 1
20. Let p (x) = x + 1 / x = 2= x + 1 = 2x= 2x - x = 1or, x = 1.let g(x) = x^3 + 1/x^3since, x = 1therefore,g (1) = (1)^3 +1 / (1)^3= 1 + 1 / 1= 2 / 1
22. Let p (x) = x + 1 / x = 2= x + 1 = 2x= 2x - x = 1or, x = 1.let g(x) = x^3 + 1/x^3since, x = 1therefore,g (1) = (1)^3 +1 / (1)^3= 1 + 1 / 1= 2 / 1= 2
24. Let p (x) = x + 1 / x = 2= x + 1 = 2x= 2x - x = 1or, x = 1.let g(x) = x^3 + 1/x^3since, x = 1therefore,g (1) = (1)^3 +1 / (1)^3= 1 + 1 / 1= 2 / 1= 2So, the answer to your question is 2.
26. Let p (x) = x + 1 / x = 2= x + 1 = 2x= 2x - x = 1or, x = 1.let g(x) = x^3 + 1/x^3since, x = 1therefore,g (1) = (1)^3 +1 / (1)^3= 1 + 1 / 1= 2 / 1= 2So, the answer to your question is 2.You can also make it this way
