# Week 16 math 10

this week in Mrs. Burtons math 10 class we learnt how to find the points on a line. To do this we need atleast two pieces of information like two coordinates. Say we have (0,5) and (3,8) this is enough information to find the point on the line. All we would need to do is first of all find the slope and secondly choose one set of coordinates and drop them into the equation were using. For this example were going to use (slope y intercept form).

This week in math we learn about the domain and the range of the quadrants. This was one of my least favourite unites because in the past, like all the other unites we learnt about its kinda just been building on what we already learnt from last year. How ever with this unite we started from scratch we had never learnt anything like this before and there for it was kinda confusing. To my understanding all of the domain is everything between the two dots on the X axel, and the range is everything between the two dots on the Y axel.

this week in math we learnt about the different quadrants and how they are different from one and the other. The top right quadrant is for all of the positive degrees, the top left quadrant is for all of the (-,+) degrees, the bottom left quadrant is for all the the negative degrees, and finally the bottom right quadrant is for the (+,-) degrees.

This week in learns how to factor difference of squares.

Difference of squares is when when you have trinomial that end in a negative and every number has a square rout. You if you do have a difference of squares you should be able to chage your trinomial into a binomial. You would be able to do this the prossese of elimination showen in the ample below.

This is considered because both of thes numbers have a square root and can be simplified.

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.
