Week 5- Factoring Polynomial Expressions



First you times he first number and times it by the last which gives you 12

After finding that find the factors of 12 and see which add together to -7 in this case -4 and -3 do.

So now you have all the numbers  put everything into the square Once you do that find the common factor of each horizontal or vertical way possible. Which are 4x, -3, x, and -1

And finally when you get those numbers you put them together and you get your answer of (4x^2 -3) (x-1)
