Question

solve
7sqrt x-1+1=x

Answer 1

\[7\sqrt{x-1} + 1 = x\]

Answer 2

yup

Answer 3

is this ur question

Answer 4

yes it is

Answer 5

49(x-1) = x^2 -2x +1
x^2 -51x +50 = 0
x = 50 or 1

Answer 6

do i type 50,1 ??

Answer 7

we have 7sqrt(x-1)+1=x
now 7sqrt(x-1)=x-1
square both sides
49(x-1)=(x-1)^2
now
(x-1)^2-49(x-1)=0
take out x-1 common
(x-1)(x-1-49)=0
(x-1)(x-50)=0
so either the first term is zero or the second term is 0
so x=1 or x=50
