Is anyone good at Algebra II?

I need help with algebra 1 canIt’s about factoring polynomials fully and factoring and stuff
what're you having trouble with, Sophie?
Okay so when you have like x squared + 4x + 3=0
How do you solve for x when you have an x squared and an x? I’m so confused 🫤
okayhas your teacher taught you about the area model method?
The problem I’m struggling with our:5x(xsquared+4x+3)=0
hmm, okay, give me a couple minutes to try and solve it for myself
Also, sorry another one, it’s one rough lesson…16m to the fourth power -81m squared =0
My dad says 9/4 -9/4 and 0 but I need to double check the computer
okay!i'm pretty positive i've got the first one
so, basically, what you do is
well, first, you need to ignore 5x
pretend it isn't there
here's what i did:
do you understand what i did?

sure, i'll be a helper. :)
Hey when I get home could I get math help

I do agree!!

That is one thing I love about math. It's logical. The answers are never going to change. 2+2 will always equal 4
@Jill, mmmm not sure if that's how that works....but sure 🤣
Has any of you done piecewise functions yet?? Like graphing them or turning a graph into one?? I'm having such a hard time

Sure! Thanks. I've kinda been getting it, but I still keep getting some wrong and I have no clue why XD

can you show me one of the problems that you are struggling with or an adjacent example? it's easier to explain math if i can get specific

Yeah sure!
They give some of the answers (I.E. -3.1), but in the lecture, she never showed it being rounded to a decimal. She just said round and it was always to a full number. So i'm not sure how I am to round to a decimal
Also sorry, this is Step Functions. XD gottem mixed up
This was the Piecewise function. I can never seem to graph it correctly
for that first one, you're just plugging in the given x values and solving the equation ( f(x) ). so that first example they gave is when x=1 creating f(x) = 1 - 4.1 = -3.1the first blank you have to fill is x=2 so f(x) = 2 - 4.1 = -2.1. considering that the examples are rounded to the first decimal, i would assume that you would also need to do that. rounding to that decimal place just involves subtracting the two values then keeping whatever decimal is left.
it looks like you are asked to digitally graph the second one, which is always annoying so good luck with that. a piecewise function is telling you that the graphed line looks different in different locations along the x-axis, so in this case the slope is 1/2 x - 3 before the x-axis reaches -2 and x+5 after crossing the y-axis.
i would recommend looking at the full graph first without the x<-2 and x>=0 restrictions first then apply it to the segment you need it for. you can use a graphing calculator or a website like desmos to do that.
here is generally what it should look like, with an open circle on -2 (because the line reaches -2 but does not include -2) and a closed circle on x=0
let me know if any of this is still confusing and i can give a better, more thorough explanation

Ohhhh okay!! That makes more sense!! Thank you!!
