You can put this solution on YOUR website!
It would be easier if you had provided and example, but here you go:
\n" ); document.write( " $\"x%5E2-x-2=0\"$
\n" ); document.write( "Factoring:
\n" ); document.write( " $\"%28x-y%29%28w%2Bz%29\"$
\n" ); document.write( "In this case, we want the first terms (x and w) to be $\"x%5E2\"$ . We want the multiplication of the outside terms (x and z) plus the inside terms (-y and w) to be -x. Finally, we want the last terms (-y and z) to be -2. A good way to remember this is F O I L = Firsts Outsides Insides Lasts
\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( "So in this case:
\n" ); document.write( " $\"x%5E2-x-2=0\"$
\n" ); document.write( " $\"%28x++%29%28x++%29\"$ *Because we need $\"x%5E2\"$
\n" ); document.write( "To get -1 we could have:
\n" ); document.write( " $\"%28x-2%29%28x%2B1%29\"$ *Because outsides (x and 1)=x + insides (-2 and x)=-2x+x=-1x=-x so that works.
\n" ); document.write( "Now to check, we FOIL:
\n" ); document.write( " $\"%28x-2%29%28x%2B1%29\"$
\n" ); document.write( " $\"x%2Ax%2Bx-2x-2=x%5E2-x-2\"$ *This is correct!!!\r
\n" ); document.write( "\n" ); document.write( "You can also solve equations like this by the quadratic formula. If you have any more questions feel free to contact me!\r
