\n" ); document.write( "Hi
\n" ); document.write( "\"%284x%2B7%29%2F%283x%5E3-5x%5E2-2x%29\"
\n" ); document.write( "the function would be 'undefined' for any value of x such that the denominator = 0
\n" ); document.write( "(3x^3-5x^2-2x) = 0 |Finding the roots of (3x^3-5x^2-2x)
\n" ); document.write( "x(3x^2 - 5x - 2)= 0
\n" ); document.write( "x(3x+1)(x- 2) = 0 Note:SUM of the inner product(1*x) and the outer product(-6x) = -5x
\n" ); document.write( " x = 0
\n" ); document.write( "(3x+1)= 0
\n" ); document.write( " x = -1/3
\n" ); document.write( "(x- 2) = 0
\n" ); document.write( " x = 2
\n" ); document.write( " x = 0,-1/3,2 are the real numbers for which the rational expression is undefined \n" ); document.write( "
\n" );
