For problem 1 multiply through by a factor of . This gets Then apply the quadratic formula (a=18, b=43, c=-5)to obtain your values for x. The second problem is similar yet you multiply through by a factor of , expand and then simplify.
I have gone back to school after 30 yrs and need a little help on a couple of problems. I know they are simple but for some reason I am have problems with these two. I can find the answers in the back of the text book but that does me no good. If someone could show me how to solve the it woould be greatly apprieciated. thanx. Here they are. I dont know how to show something is squared so I will just put the exp. after it.
1) 5/x2-43/x=18 ( the first x is squared)
2) 2=3/2x-1+-1/(2x-1)2 ( the 2x-1 is squared)
