Example Question #1 : How To Factor A Trinomial
Factor the following expression completely:
We must begin by factoring out from each term.
Next, we must find two numbers that sum to and multiply to .
Thus, our final answer is:
Example Question #42 : Variables
Factor the following trinomial:
To trinomial is in form
In order to factor, find two numbers whose procuct is , in this case , and whose sum is , in this case
Factors of :
Which of these pairs has a sum of ?
Therefore the factored form of is:
Example Question #43 : Variables
Factor the trinomial.
Our factors will need to have a product of , and a sum of , so our factors must be and .
