Question 177134
equivalent rational expression with the indicated denominator.
{{{(-7yt)/(3x)}}} = ?/18xyt
;
? = 18xyt *{{{(-7yt)/(3x)}}}
cancel 3x into 18xyt
? = 6yt *-7yt
:
? = -42*y^2*t^2
so we have
{{{(-7yt)/(3x)}}} = {{{(-42y^2t^2)/18xyt}}}
:
:
perform operation reduce to lowest terms.
{{{2/(x-3)}}} + {{{3/(3-x)}}} = {{{2/(x-3)}}} + {{{3/(-1(x-3))}}} = {{{2/(x-3)}}} - {{{3/(x-3)}}} = {{{-1/(x-3)}}}
