Algebra.Com's Answer #304550 by ptaylor(2198) You can put this solution on YOUR website! Let x=one number \n" ); document.write( "Then 4x+1=the other number \n" ); document.write( "And we are told that: \n" ); document.write( "x(4x+1)=150 \n" ); document.write( "4x^2+x=150 subtract 150 from each side \n" ); document.write( "4x^2+x-150=0 quadratic in standard form \n" ); document.write( "If we solve using the quadratic formula, we get: \n" ); document.write( "x=(-1+-49)/8 or \n" ); document.write( "x=-50/8=-25/4 \n" ); document.write( "and \n" ); document.write( "x=48/8=6\r \n" ); document.write( "\n" ); document.write( "Two solutions \n" ); document.write( "CK \n" ); document.write( "x=-25/4 \n" ); document.write( "4x+1=4(-25/4)+1=-24 \n" ); document.write( "(-25/4)(-24)=-25*-6=150 \n" ); document.write( "150=150 \n" ); document.write( "x=6 \n" ); document.write( "4x+1=25 \n" ); document.write( "6*25=150 \n" ); document.write( "150=150 \n" ); document.write( "Hope this helps--ptaylor \n" ); document.write( " |
