Week 10 math 10

This week we learnt how to factor simple trinomials and how the factor the GCF of trinomials.

Factoring simple trinomials:

To factor simple trinomials you need a trinomial that has the right pattern which I X squared + or – x + or – #. To factor this you must find two numbers that can add to the number in front of the X and can multiply the lone number.

 

Factoring the GCF:

To factore the GCF you must find the greatest common factor. Which pretty much means you must find the highest number possible that each of these numbers can be divided by.

As you can see in this example I chose 5 as my greatest common factor.

Week 8 math 10

This week in math we learnt how to simplify and expand polynomials.

First if you were looking to simplify a polynomial you would need to eliminate the brackets then group like terms together. After you’ve done so depending on weather or not the sing in front if the number is a positive or negative you will to either add or subtract the number from the like terms.

Secondly if you were looking to expaned a polynomial you would need to distribut through out it. To do this you must take the nuber out I front of the brackets and multiply it by each number inside the brackets.
