Hello,
\n" ); document.write( " My answer to the problem No.44551 will clear your doubt. However, I am reproducing the same here below: Here \"%289x%5E2-16y%5E2%29%2Fxy\" will be taken as numerator and \"%283%2Fy%29-%284%2Fx%29\" will be taken as denominator and simplified/factorised first.\r
\n" ); document.write( "\n" ); document.write( " \"%28%289x%5E2-16y%5E2%29%2Fxy%29%2F%28%283%2Fy%29-%284%2Fx%29%29\" After factorising the numerator and simplifying the denominator, we get,
\n" ); document.write( "
\n" ); document.write( " \"%28%283x%2B4y%29%283x-4y%29%2Fxy%29%2F%28%283x-4y%29%2Fxy%29\". This means the numerator divided by the denominator. For dividing, we multiply the numerator by the inverse of the denominator. So,
\n" ); document.write( "
\n" ); document.write( " \"%28%283x%2B4y%29%283x-4y%29%2Fxy%29%2A%28xy%2F%283x-4y%29%29%29\" = \"%28%283x%2B4y%29%283x-4y%29xy%29%2F%28xy%2A%283x-4y%29%29\" =
\n" ); document.write( "
\n" ); document.write( " \"3x%2B4y\" Answer. I hope this is clear to you now. \r
