how do you use the x-box method if there is a number in front of x^2?
how do you use the x-box method if there is a number in front of x^2?
Almost exactly like before, except you have an extra step in the beginning and an extra step at the end!
Let's talk about how to factor using the X-Box Method:
Let's talk about how to factor using the X-Box Method:
The Steps (take out any GCF before you start):
In the top box, write the product of a and c
In the bottom box, write b (just like before)
Find two factors of ac that add up to b (just like before)
Write your two binomials (just like before, except the first two numbers won't just be x and x. You will need to check these by refoiling! The position matters.)
