4rt(x-1)=x-1
squaring gives
16(x-1)=(x-1)(x-1)
gives x^2 -18x +17
factorise gives x=17 x=1
hope this helps.
I am 42 years young and trying to brush up my 25 year old shelved algebra knowledge.
I am stumped with this problem.
I have the answer, but I don't know how to get there exactly. I know I will have to square both sides and that it will wind up as a Quad equation, but I am sooo lost on how to get there.
Please help! Thanks!
