Question

Your friend runs up to you, scared that he is not ready for the upcoming quadratics test. To help him study, you will create four different quadratic functions. Then demonstrate to him how to rewrite each function as a group of factors, if possible.
The function f(x) is a difference of squares.
The function g(x) is a sum of squares.
The function h(x) is a perfect square trinomial.
The function j(x) can only have a GCF factored out of it.

Answer 1

I just don't know the sum of squares part lol

Answer 2

If the difference of squares equals, say, (x+3)(x-3), then I think I think the sum of squares = (x+3)(x+3).

Answer 3

Delete the one "I think" out of that sentence... XD

Answer 4

Weird. Never heard of that.

Answer 5

What is a trinomial that only can have a GCF factored out and nothing else?

Answer 6

Nevermind I got one

Answer 7

Ja, I've never heard of the some of squares before either... >.>

Oh, ok. XD I was busy looking it up just to make sure, lol.

Answer 8

I literally just wrote an equation huge
400x^2+200000x-50000 lol
GCF 400

Answer 9

Given the function k(x) = x^2, compare and contrast how the application of a constant, c, affects the graph. The application of the constant must be discussed in the following manners:
k(x + c)
k(x) + c
k(cx)
c • k(x)

Answer 10

LOL
But yeah, that looks correct...

Answer 11

Well, I can say for certain sure that in k(x) + c, the value of c determines the y intercept, so it shifts the graph up or down the y-axis.

Answer 12

Hmm... I knew that but idk about the others.

Answer 13

As for the others, maybe this helps?

If y = A (Bx + C ) + D
C = vertical shrink, by a factor of "C"
B = vertical shrink, by a factor of "B"
D = vertical shift, D > 0, up, D < 0, down

Answer 14

I found this other question on OS that is the same: http://openstudy.com/study#/updates/525452b3e4b037f058866156

jdoe seems to have put it well. xD

Answer 15

It's 4:40 a.m and I still hate math

Answer 16

I never understood why I agree to do peoples homework for free lol

Answer 17

LOL
At 4:40 a.m., I hate math myself. xD
I remember sitting up trying to do trig at 2 a.m. and it was awful xD
But I'm finished maths for school now... ^-^

Answer 18

Lucky you, I'm in calc 3 then I have to finish up statistics then I have to do my grad level math courses:/

Answer 19

e.e
That sounds... nasty. XD
I have to take a mathematics course next year in university as well. Some days I dread this, and some I actually look forward to it. o.o
LOL

Answer 20

Never look forward to math. Ever. My past math test was so hard I literally screamed of happiness that I got a 60

Answer 21

So stupid. They made one of my engineering classes like crazy grading. If you had a 35% in the class, you got an A. That means you only have to know 35% of the information?!

Answer 22

I wrote my final maths exam like three weeks ago, and I was like, oh, I hope I passed >.>
I still don't know. xD

35%?! Darn... If I got less than a 50%, I failed. I had to know every single little nugget of information hidden between the lines in my book, plus what they never told me, but still expected me to know.

Answer 23

As well as I lost marks if I didn't set out my work just right.

Answer 24

Haha it's only for engineering classes. If not, the pass rate I think he said would be 1 in 800

Answer 25

XD
Well, I must be going as I have three more upcoming exams to study for... e.e
Hopefully that other question helped a bit... xD
