Example 4 Quotient of Two Trinomials


Example 4 1a

Factor

The GCF is 5ab.

Answer:

Distributive Property

Example 4-1a


Example 4 1b

Factor

Answer:

Example 4-1b


Example 4 2a

Factor

Group to find the GCF.

Factor the GCF of each binomial.

Answer:

Example 4-2a


Example 4 2b

Factor

Answer:

Example 4-2b


Example 4 3a

Factor

Product –15 and sum is –2.

Substitute –5y+ 3y for –2y.

Review

Example 4-3a

Rewrite the expression using –5yand 3y in place of –2yand factor by grouping.


Example 4 3b

Factor out the GCF of each group.

Answer:

Associative Property
