Step 1: Write each term as a "true" fraction
Step 2:
Quadratic formula.
Suppose you want to solve a quadratic equation (youll recognize it because it will have an x 2 as
the highest degree).
In standard form it looks like this ax2 + bx + c = 0
This formula will ALWAYS work. Some people prefer to factor and
To find LCD of two expressions you must factor both expressions first.
Then you must use all of the factors.
You use each factor the most number of times it occurs in either one of the expressions.
2a2 + 4a + 2
= 2(a2 + 2a + 1)
= 2(a + 1)(a + 1)
= 21(a +
Factoring Summary - if this were a f-2-f class, these are the examples
we would work on the board. Therefore, I strongly urge you to copy each of them
by hand and then use it as a guide when you practice, practice, practice.
