Warm Up
Multiply:
Objective
The student will be able to factor by distribution,
grouping and factor trinomials.
Think, Pair, Share…
I have the polynomial: 9x2 + 36x and I would like
to know what two polynomials were multiplied
together to create this binomial, could I figure
this out? If so, how if not why not?
Factoring by the
Distributive Property
Factor:
1st find the GCF.
2nd write each term as a product of the GCF.
3rd use the distributive property to factor out the
GCF.
Factoring by Grouping
Factor:
1st group terms with common factors.
2nd factor the GCF from each grouping.
3rd distributive property.
Factoring using the
Additive Inverse
Factor:
1st group terms with common factors
2nd factor the GCF from each grouping
3rd simplify
4th distributive property
Zero Product Property
If the product of two factors is 0, then at least
one of the factors must be 0.
ab = 0 then, either a = 0 or b =0.
Solve an Equation in
Factored Form
Solve:
1st set each equation to zero.
2nd solve.
