Isolate the more complicaed radical term. So we
isolate
Square both sides:
Write the square on the right as the product
of the binomial with itself:
Use FOIL on the right sides:
Isolate the radical term:
Square both sides:
Get 0 on the left:
That doesn't factor, so we have
to use the quadratic formula:
, ,
Make two fractions:
Those have decimal values
Check these in the original with a
calculator. The first one doesn't
check but the second one does.
So the only solution is
