## Section 8.5 Notes

CPM

Solving an equation, such as requires a new property…………

Power Property of Equality: If a=b, then an=bn. But the new equation may have extraneous solutions

You have to get the square root by itself before you can square it.

NO SOLUTION

A square root can never equal a negative #

Change this problem

Now we have to factor and use the zero product property

X=7 is the only solution. X=1 was extraneous.
