Week 5 – Factoring Polynomial Expressions

This week in pre-calculus 11, we started to learn how to factor polynomial expressions. When we first started learning about factoring polynomial expressions, it was fairly straight forward, as it was questions such as x^2-81. This is a straight forward expression because it is a difference of squares. When factoring this type of expression, you find out what the perfect squares are. Therefore, for this question, it is obvious that the factored answer is going to be (x-9)(x+9).

Here is a more challenging expression and here are the steps for how to factor it.

2x^2-50y^2

 

2(x^2-25y^2)

 

2(x-5y)(x+5y)

And those are the steps of factoring polynomials. Thanks for reading! Hope you learned something.
