4. Unit 1.3-1.5 graphing equations
• The reason that I like this unit so much is
that this is the first unit that we got a
project on and it was very cool. In this unit
we created a pic and converted it to
graphing paper. I ended up making the
Texas flag and one of my friends made a
medieval castle!
5. Unit 1.8Writing equations given points and
slopes
• If you are given slope and a point, then it
becomes a little trickier to write an equation.
Although you have the slope, you need the y-
intercept. I always hated this unit because it
took so many steps over something that
should take no time at all.
6. Unit 3.15 Quadratic regression
• Quadratic Regression is a process by which the
equation of a parabola of "best fit" is found for
a set of data. I found this interesting because it
meant that quadratics weren't as cut and dry
as I thought, also it can be used to answer
graphs to a better extent. For example the pic
shows the line of best fit even though it does
not cross all the points.
7. Unit 3.9: Complex Numbers
• A complex number is a number that can be
expressed in the form a + bi, where a and b are
real numbers and i is the imaginary unit, which
satisfies the equation i2 = −1. this makes little
to no sense how can a imaginary number
squared give me -1 so
(10239843928i) (10239843928i) is -1?
8. Unit 4.1b negative exponents
• negative exponent just means that the base is
on the wrong side of the fraction line, so you
need to flip the base to the other side. For
instance, "x–2" (X to the minus two) just means
"x2, but underneath, as in 1/(x2 ). I thought that
this was particularly funny as it seemed to me
that the equation was a mistake. I would
always laugh to my self because it made me
wonder how the guy that discovered this
theory got to these negative exponent's.
9. Unit 4.4: Operations with Radicals (2 days)
• I hate this unit because this displays a working
of math that I don’t understand and we just
learnt the formula so its very troubling to try to
understand what is going on.To combine them
you need to make the radical little number the
same than you multiply the inside only.
confusing yes I know.
10. Unit 6.5-6.7 logs and exponents
• The exponent of a number says how many
times to use the number in a multiplication. In
this example: 23 = 2 × 2 × 2 = 8 A Logarithm
says how many of one number to multiply to
get another number. I liked this because it
shows to me that everything in math is
interchangeable.To me it seems that log and
exponent's are in a relationship!
11. Unit 8.4: Synthetic Division
• I don’t understand this unit very well but I’ll try
to explain. In synthetic dividing you set the
divisor equaled to 0 and then you put the
number before each X( so X^2+3X+7 is 1,3,7)
than you bring down the first number
subtracting one X than you multiply it by the
divisor and add it to the next number and
repeat until you run out of numbers. If you get
anything other then a 0 then the divisor is not
a factor.
12. How to pass algebra 2
• There are 5 things you need to be successful in
algebra 2
1. Always pay attention in class
2. If you need help don’t be afraid to ask.(or go
to tutorials)
3. Do the practices (they’re not homework but
they still benefit you a lot)
4. Always bring a pencil or BLACK pen(no pink
pens sorry guys)
5. Have a (positive) attitude
13. Algebra 2 IRL (in real life)
Here’s an example lets say you are all grown up now and have to move across
country for a new job. Lets use Buffalo, NY to Sacramento, CA which is
roughly 2500 miles of driving. How much money do you need to save for gas if
the national average is $3.23/gallon.
Let x = amount of money you need to save
2500 = 3.23x
x=$773.99
14. congrats
With this amazing guide you will easily ace algebra 2
(however I am not responsible if you failed that’s on you man)
