Form the conjugate of the denominator,

The conjugate of a two-term expression

has the same first term, but the second

term has its sign changed.  So the

. So put this over

itself like this 

which just equals to 1.  Now multiply the 

original expression by that:







Now put parentheses around every expression with two terms:







Put it all as just one fraction







Distribute out the top, and FOIL out the bottom:







Notice that , , , and 









The two radical terms in the bottom cancel out and we just have







or just
