\n" ); document.write( "\n" ); document.write( "Length: $\"3x-4\"$
\n" ); document.write( "Area: $\"6x%5E4-8x%5E3%2B9x%5E2-9x-4+\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"Area=Length%2AWidth\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"Width=Area%2FLength\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, you need to divide $\"6x%5E4-8x%5E3%2B9x%5E2-9x-4+\"$ by $\"+3x-4\"$ to find the width\r
\n" ); document.write( "\n" ); document.write( " $\"%286x%5E4-8x%5E3%2B9x%5E2-9x-4%29%2F%283x-4%29\"$ ....factor numerator completely\r
\n" ); document.write( "\n" ); document.write( " $\"%286x%5E4-8x%5E3%2B9x%5E2-6x-3x-4%29%2F%283x-4%29\"$ .....write $\"-9x\"$ as $\"-12x%2B3x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%28%286x%5E4-8x%5E3%29%2B%289x%5E2-12x%29%2B%283x-4%29%29%2F%283x-4%29\"$ .......group\r
\n" ); document.write( "\n" ); document.write( " $\"%282x%5E3%283x-4%29%2B3x%283x-3%29%2B%283x-4%29%29%2F%283x-4%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%28%283+x+-+4%29+%282+x%5E3+%2B+3+x+%2B+1%29%29%2F%283x-4%29\"$ ....simplify\r
\n" ); document.write( "\n" ); document.write( " $\"2+x%5E3+%2B+3+x+%2B+1\"$ => your answer for the width\r
