Algebra.Com's Answer #212680 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! If the solutions are a and b the the equation is (x-a)*(x-b)=0 \n" ); document.write( "a=1/2 and b=10/3 \n" ); document.write( "(x-1/2)*(x-10/3)=0 \n" ); document.write( "Use FOIL to multiply it out. \n" ); document.write( "F x^2 \n" ); document.write( "O -10x/3 \n" ); document.write( "I -x/2 \n" ); document.write( "L -1/2*-10/3=10/6 \n" ); document.write( "add them all together \n" ); document.write( "x^2-10x/3-x/2+10/6=0 \n" ); document.write( "We could multiply by 6 \n" ); document.write( "6x^2-20x-3x+10=0 \n" ); document.write( "6x^2-23x+10=0 \n" ); document.write( " \n" ); document.write( " |
