# Simplifying a square root?

Asked by tranquilsea (17760)
April 28th, 2011

My mind, for some unknown reason, is drawing a blank as to why this is so:

If I have an expression: 28 + 7 square root of 2 over 14…why is the simplified expression 4+ the square root of 2 over 2?

What factor is used to knock the seven out and leave the 4 over the 2?

This is almost as bad as when I forgot how to spell “the”. *That was a bad day*
