HELP ME!! with math

OpenStudy (chrisg094):

\[3+\sqrt{2x-3}=x\]

OpenStudy (chrisg094):

solve the radical equation.

OpenStudy (chrisg094):

Then I need help with another one too.

OpenStudy (chrisg094):

It says, find the domain of the square root function. Write the answer in interval notation \[f(x)=\sqrt{12-4x}\]

OpenStudy (chrisg094):

@DariusX can you help me with this problem

OpenStudy (seeing.in.pixels):

I don't know if you want it, but I'd be glad to offer my help!

OpenStudy (chrisg094):

Give it a shot.

OpenStudy (seeing.in.pixels):

Okay, let's start with the first one.

OpenStudy (seeing.in.pixels):

What are you trying to do with the equation? Solve for x?

OpenStudy (anonymous):

First subtract 3 from both sides, then square it.

OpenStudy (chrisg094):

I think it just says solve the radical equation. It doesn't specify much

OpenStudy (seeing.in.pixels):

no that will still leave you with two unlike x terms

OpenStudy (chrisg094):

@reaganchoi that is smart, total missed that.

OpenStudy (seeing.in.pixels):

closet you can get with that is \[6=x ^{2}-x\]

OpenStudy (chrisg094):

Oh, wait IDK. I truly need help.

OpenStudy (adrianna.gongora):

Isn't it 6=x

OpenStudy (seeing.in.pixels):

I have a nerd for a dad. His job is math. If you wait just one sec i'll be right back with his answer

OpenStudy (chrisg094):

That sounds GREAT!

OpenStudy (adrianna.gongora):

\[x ^{2}-x\] is equal to x which ends up being x=6

OpenStudy (seeing.in.pixels):

Okay, based on this equation, you must be learning quadratics which I hadn't thought o until my dad and I conferred. Anyway, \[ax ^{2}+bx+c\] sounds like your formula for your solution

OpenStudy (chrisg094):

That sound about right, I do remember that formula from my last class.

OpenStudy (adrianna.gongora):

I'm so lost now I thought I had it right... .___.

OpenStudy (chrisg094):

I know @Adrianna.Gongora I was doing it the same exact way you was but its different.

OpenStudy (adrianna.gongora):

I think I did it wrong cause there was no parenthesis around the x part

OpenStudy (chrisg094):

its the way @Seeing.In.Pixels is saying

OpenStudy (chrisg094):

That is the way its given to me

OpenStudy (seeing.in.pixels):

Glad to help. Shall we move on to the second problem, or do you understand?

OpenStudy (chrisg094):

No wait, I don't know how to get the problem done. Is it the way @Adrianna.Gongora was saying? or no. I do remember the formula but for some reason I so lost with this problem.

OpenStudy (seeing.in.pixels):

Alrighty then. Let's try this again.\[3+\sqrt{2x-3}=x\] We know that we want our answer in the form I mentioned before, right? So let's try to do that. the x's need to be together, so start by squaring both sides to make that possible.

OpenStudy (chrisg094):

So the 3 will need to be subtracted to the other side right.
