Blog Log – Fake news

https://www.nytimes.com/2018/03/08/technology/twitter-fake-news-research.html

This article was very interesting for me because it was about an MIT study about human behaviour regarding fake news and real news and how fake news will spread quicker on social media than real news.  The author of the article illustrates that fake news tends to spread more because it the news is falsified in order for it to become more interesting.  Of course when an article is more interesting people will share it more on social media.  I think most of us, including myself, have come across a piece of fake news on the internet and were enticed to learn more contrary to real news which contains a more boring tone.  This study exemplifies human nature and the way we, as humans, process information we see online.  The article also mentions that it is very important know the source of news story and think for yourself if what you are reading is reliable and believable.  This type of human behaviour is applicable not only to news; for me, I tend to do this for anything I see online.  If it looks interesting, I’ll learn more about it, and if it doesn’t look interesting I will not learn more.

Week 6 – Solving quadratic equations by factoring

When you have the equation ax^2+bx+c=0 you can solve for x by factoring this equation

Ex. x^2+8x=-15

=x^2+8x+15=0

Now that we have the factorable equation into the form we want, we are now able to factor it into two binomials so that when we multiply them it equals ar equation.

(x+3)(x+5)=0

We can see now that x has two possible answers because when one of the binomials equals zero than we still have 0 on the other side since n*0=0.  So, we know that our two possible values for x are -3 and -5 because when we add them back into the equation, we get 0.

Week 5 – factoring polynomials

This week in Math, we learned how to factor polynomials.

Ex. 8x^2-32

If we want to factor this, we must remove a common factor from each term.  In this case, a common factor is 8.

8(x^2-4)

This is factored, but it is not factored all the way because we can see that there is a difference of squares in the brackets.  To simplify this, we must multiply conjugates.

8(x+2)(x-2)

This is now the factored form of 8x^2-32
