Question

Our professor never showed us how to work this out. I checked the internet and was told there was no solution, but how would you work this out?

5(x-1)+3squareroot(x-1)-2=0

Answer 1

5(x - 1) - 3(x - 1)^(1/2) - 2 = 0
so x = 2.

Answer 2

5 ( 2 - 1) - 3 (2 - 1)^(1/2) - 2
= 5 (1) - 3 (1)^(1/2) -2
= 5 - 3 - 2
= 0
