Unit 4 (MAT136)

Unit 4 (MAT136)
The largest term we can divide everything by
On variables yse the loweest exponent - ANS-CGF

a (b+c)=
Put greatest common factor in front and divide. What's left goes in the parenthesis. - ANS-GCF
Grouping-Factor

GCF of left and right. Then factor out binomial GCF - ANS-GCF Grouping

If binomials don't match move second term to the end. - ANS-GCF- Terms don't match

If there is a 1 in front of x2, the ac method gives us the factors - ANS-Trinomial A=1

Always go GCF first! - ANS-Trinomial GCF

ax^2 +bx +c
Find a pair of numbers that multiply to ac and add to b.

Using FOIL, O and I - ANS-A doesn't equal 1

Always Prime. Doesn't factor - ANS-Special Products- Sum of Squares

We use difference of squares twice - ANS-Special Products 4th Power

Using the ax method if the numbers match factor to a perfect square - ANS-Special Product-
Perfect Square

Identify cube root
