OpenStudy (helder_edwin):

if u solve the equation u have, by squaring \[\large \sqrt{4x-6}=\sqrt{x} \] \[\large 4x-6=x\] \[\large 3x=6 \] \[\large x=2 \] right?

OpenStudy (anonymous):

Correct !

OpenStudy (helder_edwin):

now, if u replace x=2 into the original equation, does it actually solve the equation?

OpenStudy (helder_edwin):

i.e., is it a valid solution?

OpenStudy (anonymous):

Yes :o

OpenStudy (helder_edwin):

so, is it extraneous or non-extraneous?

OpenStudy (helder_edwin):

i.e., it is non-valid (extraneous) or valid (non-extraneous)? http://en.wikipedia.org/wiki/Extraneous_and_missing_solutions

OpenStudy (anonymous):
