For all r is not equal to plus or minus 2, (r squared - 5r + 6) over (r squared - 4 = ?
\n" ); document.write( "What does it mean \"for all r is not equal to plus or minus 2\"?
\n" ); document.write( "----------------------
\n" ); document.write( "Problem:
\n" ); document.write( "(r^2-5r+6)/(r^2-4)
\n" ); document.write( "----
\n" ); document.write( "Factor this rational expression:
\n" ); document.write( "[(r-3)(r-2)]/[(r-2)(r+2)]
\n" ); document.write( "===================================
\n" ); document.write( "What does it mean \"for all r is not equal to plus or minus 2\"?
\n" ); document.write( "Ans: Since the denominator would be zero if r = 2 or if r = -2,
\n" ); document.write( "those values of r are not allowed.
\n" ); document.write( "=============================================
