Question 73492
{{{(y-3)*(y+5)}}}I assume the problem looks like this
{{{y*y+5*y-3*y-3*5}}}The factors FOIL to this
{{{y^2+5y-3y-15}}} Multiply each term
{{{y^2-2y-15}}}Subtract like terms. This is your answer.
<p>

If it looks like this {{{(y-3)*(yt^5)}}} then
{{{(y-3)*(yt^5)}}}
{{{(yt^5)*y+(yt^5)*(-3)}}}Distribute the {{{(yt5)}}} to every term
{{{y^2t^5-3yt^5}}}This is your answer if the problem looks like {{{(y-3)*(yt^5)}}}

Hope this helps.
