I NEED SOMEONE GOOD AT ALGEBRA TO DM ME PLSS HURRY DEADLINE IS VERY SOON!

darkknight:

post ur questions here

NevaehJade6219:

i cant put a pic here though well if i can idk how

right now you have your function in vertex form, we can rewrite this 4(x+1)^2 -3 What do you think is the first step?

darkknight:

I am walking it through with you step by step, so you know how to solve problems like this inthe future

NevaehJade6219:

O_O

\(\color{#0cbb34}{\text{Originally Posted by}}\) @darkknight I am walking it through with you step by step, so you know how to solve problems like this inthe future \(\color{#0cbb34}{\text{End of Quote}}\) to label the a b and c of the equation?

darkknight:

hmm ok, well what happens when you expand the square (x+1)^2 do u know how?

darkknight:

well we would need to find a, b and c first, thats our first step

NevaehJade6219:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @darkknight hmm ok, well what happens when you expand the square (x+1)^2 do u know how? \(\color{#0cbb34}{\text{End of Quote}}\) nope that why i asked this question

darkknight:

alright, so order of operations, first parenthesis, then exponents, than multiplication/division then addition/subtraction

NevaehJade6219:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @darkknight alright, so order of operations, first parenthesis, then exponents, than multiplication/division then addition/subtraction \(\color{#0cbb34}{\text{End of Quote}}\) PEMDAS!!!!!!!!!!!!!!!!!!

darkknight:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @darkknight right now you have your function in vertex form, we can rewrite this 4(x+1)^2 -3 What do you think is the first step? \(\color{#0cbb34}{\text{End of Quote}}\) So you see here, the first step would be to expand the square, since we cant simplify anything within the parenthesis and yes pemdas! Since (x+1)^2 has an exponent, this is what we simplify first

darkknight:

\[(x+1)^2=(x+1)(x+1)\] you can then distribute that above or use the formula \[(a+b)^2 = a^2+2ab+b^2\] where a is x and b is 1 in this case

NevaehJade6219:

noooooooooo thats why i askeddddddd. hmmm distrbute. nope idk how

NevaehJade6219:

bro i be livin in rona world idk anything anymore

darkknight:

well we would actually use FOIL, if you have heard of it, First, then inner, then outer then last what this means is that we take the first 2 terms and multiply, then add the product of the inner terms, then add the product of the outer 2 terms and then add the product of the last 2 terms

darkknight:

this in action would look something like thi|dw:1615396832257:dw| this is an example problem of how foil works, so I had (x+2)(x+5) I labeled the arrows by order, although it isnt the end of the world if u dont do it in the right order , its good to have your work organized, so take my advice its the easiest way So we do first: x times x we get x^2 outer : x times 5 we get 5x (these are the outer 2 terms) inner: 2 times x we get 2x (these are the inner 2 terms) last: 5 times 2 we get 10 (these are the last 2 terms)

apologize for the legendary handwriting ahead of time :)

NevaehJade6219:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @darkknight apologize for the legendary handwriting ahead of time :) \(\color{#0cbb34}{\text{End of Quote}}\) hehehe its ok

darkknight:

tell me when you understand what we did in that sample problem, (x+1)(x+1) involves close to the same steps, if you have more questions ask away!

NevaehJade6219:

darkknight:

no thats the problem you are trying to solve, forget about that, focus on the sample problem (x+2)(x+5) \(\color{#0cbb34}{\text{Originally Posted by}}\) darkknight this in action would look something like thiCreated with RaphaëlReply Using Drawing this is an example problem of how foil works, so I had (x+2)(x+5) I labeled the arrows by order, although it isnt the end of the world if u dont do it in the right order , its good to have your work organized, so take my advice its the easiest way So we do first: x times x we get x^2 outer : x times 5 we get 5x (these are the outer 2 terms) inner: 2 times x we get 2x (these are the inner 2 terms) last: 5 times 2 we get 10 (these are the last 2 terms) \(\color{#0cbb34}{\text{End of Quote}}\)

NevaehJade6219:

O_O

NevaehJade6219:

ugh im done

darkknight:

please dont give up, we got this, and when i say we i mean u and me. read it slowly, if u need help with anything ask away,ask the parts you dont understand or need clarification

NevaehJade6219:

thx for the help.

darkknight:

we rnt done yet

NevaehJade6219:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @darkknight we rnt done yet \(\color{#0cbb34}{\text{End of Quote}}\) yea ik i just cant my head is like anfaoidnf paoid faosdifno andsfoasdaosdf

darkknight:

how about you take a break, its not too hard of a problem, you got it. Take like a 15 min brake and cool off, refresh your mind

NevaehJade6219:

darkknight:

... you are wasting your own effort and mine too :\ your choice in the end though,

\(\color{#0cbb34}{\text{Originally Posted by}}\) @darkknight ... you are wasting your own effort and mine too :\ your choice in the end though, \(\color{#0cbb34}{\text{End of Quote}}\) im just gonna go on a diffrent question those are to hard
