Algebra.Com's Answer #422708 by funmath(2933) ![]() You can put this solution on YOUR website! Factor 7x^2-14x-56\r \n" ); document.write( "\n" ); document.write( "First factor out the greatest common factor. In this case all three terms are divisible by 7. \n" ); document.write( " \n" ); document.write( "Now we know that we have: \n" ); document.write( "7(x+___)(x-___) Because the last term is negative. \n" ); document.write( "We need to find to numbers that multiply to give -8 (the last term) but add to get -2 (the middle term) \n" ); document.write( "-4*2 = -8 and -4+2=-2 \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " I think the next one might be a type-0, so I will do it as you wrote it, then do it based on my experience of what the type-o might be. \n" ); document.write( "factor 9x^2-336x+27 \n" ); document.write( "The all numbers are divisible by 3. \n" ); document.write( " \n" ); document.write( "That's all you can do.\r \n" ); document.write( "\n" ); document.write( " I think you meant: \n" ); document.write( "factor \n" ); document.write( "Everything is divisible by 9 \n" ); document.write( " \n" ); document.write( "-3*-1=3 and -3+-1=-4 \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hope that helped. Happy Calculating. \n" ); document.write( " |
