Algebra.Com's Answer #94510 by apachemexican1(64)![]() ![]() ![]() You can put this solution on YOUR website! x^2-(3x+4)=(x+8)(x-5) \n" ); document.write( "First use foil \n" ); document.write( "x^2-(3x+4)=x^2-5x+8x-40 \n" ); document.write( "then combine like terms \n" ); document.write( "x^2-3x-4=x^2+3x-40 \n" ); document.write( "now move all x's to one side of the \n" ); document.write( "equation and regular numbers to the other \n" ); document.write( "to make an equation. \n" ); document.write( "x^2-x^2-3x-3x=-40+4 \n" ); document.write( "now add or subtract like terms \n" ); document.write( "-9x=-36 \n" ); document.write( "now divide -9 to both sides \n" ); document.write( "-9x/-9=-36/-9 \n" ); document.write( "x=4\r \n" ); document.write( "\n" ); document.write( "good luck!!! \n" ); document.write( " |
