Algebra.Com's Answer #499065 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! look at some consecutive odd numbers \n" ); document.write( "5 7 9 11 \n" ); document.write( "they are two a part \n" ); document.write( "so we let x be the first and x+2 be the second \n" ); document.write( "x*(x+2)=143 \n" ); document.write( "x^2+2x-143=0 \n" ); document.write( "what are factors of -143? \n" ); document.write( "-11 and +13 \n" ); document.write( "and \n" ); document.write( "+11 and -13 \n" ); document.write( "we need them to add up to +2\r \n" ); document.write( "\n" ); document.write( "(x-11)*(x+13)=0 \n" ); document.write( "x=11 y=13 or x=-13 y=-11 \n" ); document.write( "remember their products must be +143 \n" ); document.write( " \n" ); document.write( " |
