### The Nature of Roots

# THE NATURE OF ROOTS

Before I start talking about the nature of roots...Let's have a short review of

**what roots are and how can we get them.****are where the quadratic "crosses/touches" the x-axis. It's an x-intercept or zeroes.**

__Roots:__**We can get the roots by:**

1.) factoring

2.) quadratic formula

3.) or completing the square.

Okay, for those who didn't know that... Now you do ;)

and now to the...

**The Sum and Product of Roots.**

*sum of the roots*is the

**negative**or

**opposite**of b (coefficient of x).

-The product of the roots is c (constant term).

**EXAMPLE:**

b (coefficient of x) is (-6), it is the negative/opposite of the sum of the roots.

c (constant term) is (8), it is the product of the sum of the roots.

THE SUM OF THE ROOTS IS : -**b/****a**

__b (coefficient of x)__

a (leading coefficient)

**c/a**

__c (constant term)__

a (leading coefficient)

**EXAMPLE:**

okay... this is it!

no exercise homework... just the worksheet handout on nature of roots =)

bye for now!

ANNNND the next scribe is....oliver.
