How do you solve these kind of radicals:

1. (5-{14)*(3-{2)

2. (4{2+2)*(3{3-1)

Can someone show me how to do these correctly please ?

**Reiny**, Wednesday, January 14, 2009 at 11:41pm1. (5-{14)*(3-{2)

I read that as

(5 - √14)(3 - √2)

= 15 - 5√2 - 3√14 + √28

= 15 - 5√2 - 3√14 + 2√7

2. (4{2+2)*(3{3-1) is it..

(4√2 + 2)(3√3 - 1) ??

= 12√6 - 4√2 + 6√3 - 2
