Lesson 10.3 WarmUp:
Determine how many solutions the following
equations have:
1) 2x2 ­ 7x = ­2
2) x2 + 25 = ­10x
3) x2 + 2x + 5 = 0
Use the Quadratic Formula to solve the
following:
4) x2 ­ 4x = 12
5) x2 + 20 = 12x

Lesson 10.3:
*To add or subtract radical expressions... the radicands must be alike!
(similar to "like terms")
...And, when adding or subtracting them, the radicands don't change!
ex­­> 4 5 + 2 5 =

4. Lesson 10­3.notebook March 13, 2014
*We can also use the distributive property to simplify radical
expressions!
ex ­­> 3 5 (2 5 + 5 3) =
