x^2+2x-48=0\r
\n" ); document.write( "\n" ); document.write( "You will need to use Reverse FOIL
\n" ); document.write( "A. Set your parenthesis (excuse the lines inside, if I don't do that it will look like this () which is confusing.)\r
\n" ); document.write( "\n" ); document.write( "(__)(__)\r
\n" ); document.write( "\n" ); document.write( "B.Now ask yourself, what multiplied by what will give you x^2? x multiplied by x will give you x^2.
\n" ); document.write( "When using FOIL, this would be the F in the word FOIL (First)
\n" ); document.write( "(x__)(x__)\r
\n" ); document.write( "\n" ); document.write( "C. Now ask yourself, what multiplied by what will give me -48 but added together will give me 2?
\n" ); document.write( "Answer: -6 multiplied by 8 will give me -48 and when you add -6+8 together you will get 2.
\n" ); document.write( "This step provides for the OIL in FOIL (outside, inside last)
\n" ); document.write( "(x-6)(x+8)=0
\n" ); document.write( "(If you foil that you will get your original equation.)\r
\n" ); document.write( "\n" ); document.write( "No set both equal to zero:
\n" ); document.write( "x-6=0 which is x=6
\n" ); document.write( " and
\n" ); document.write( "x+8=0 which is x=-8\r
\n" ); document.write( "\n" ); document.write( "So you have:
\n" ); document.write( "x=6 and x=-8 \n" ); document.write( "
