This week in math 11 I learned about the quadratic formula.

the quadratic formula looks like this :

in order to fill in the variables you need to know what is what.

so when you’re looking at an equation it will look like

a + bx + c = 0.

your a variable is obviously the number in front of the but if there is no number in front of it, a = 1. b is the second variable and it is the one in the middle of the equation and c is separate on its own.

It takes more time then completing the square and factoring but it is a good way to get the correct answer since you fill in all the variables and get a more direct answer.

This week in math 11 we learned about absolute values. A absolute value is always positive so if you have  |-6| then your answer would be 6.

In this example I have the equation so we know that 2 – (-8) would turn into 2 + 8 so our numerator would be 10. Then we would have |3| – |-2| since -2 is an absolute value it is changed into 2. then we have 3 – 2 = 1.

so our fraction is = 10

.

Another example is | + 6x – 5|, x = 2

So if X = 2 then we know = 4 and 6 x 2 = 12

|4 + 12 – 5|

4+ 12 = 16

16 – 5 = 11

= 11
