Question

3sqrt{x-1}+1=x

Answer 1

draw it out please.

Answer 2

ok

Answer 3

\[3\sqrt{x-1}+1=x\]

Answer 4

(x-10)*(x-1)=0
x=10 or 1.

Answer 5

actually, just say its 10. If you plug in 10 for x, you'll get it to be correct.

Answer 6

no its not right

Answer 7

\[3\sqrt{x-1}+1=x\]
\[3\sqrt{x-1}=x-1\]
squaring on both sides
\[(3\sqrt{x-1})^2=(x-1)^2\]
\[9(x-1)=x^2-2x+1\]
\[9x-9=x^2-2x+1\]
\[x^2-2x-9x+1+9=0\]
\[x^2-11x+10=0\]
\[x^2-10x-x+10=0\]
\[x(x-10)-1(x-10)=0\]

\[(x-1)(x-10)=0\]
\[x=1,x=10\]
