Algebra.Com's Answer #279142 by ptaylor(2198)![]() ![]() You can put this solution on YOUR website! Then we have: \n" ); document.write( "(x-3)(x+4)=0 expand using FOIL \n" ); document.write( "x^2+x-12=0 Now this quadratic has to be identical to x^2+ax+b, so: \n" ); document.write( "a=1 \n" ); document.write( "b=-12\r \n" ); document.write( "\n" ); document.write( "Hope this helps---ptaylor \n" ); document.write( " |
