Hi as you can see this is indeed my first post on this forum and this is because of the mass difficulty i am having with these type of questions i understand the basic quadratics with the -b formula.But these questions are confusing me so much i would appreciate if somebody has to time to go through this fully.
This is located in the Algebra 2 Chapter
I would appreciate if someone could help me, i think with about 3 or 4 Qsts explained it could help me to do the rest.

Q.4 https://gyazo.com/af2fdd055582a44ae4061e727e53311f

If anybody has any other tips on how to upload equations on the forums please inform me

Thanks

I'm not certain of this, but it seems based on the four examples you've posted that your difficulty isn't so much with the quadratic formula, as it is rearranging the equation to form a quadratic in the first place. If I'm wrong about this, then when you reply back please include exactly where you think the process is going sideways for you.

Assuming my initial interpretation was correct, let's look at the first example:

\(\displaystyle \frac{1}{x+1}+\frac{1}{x}=\frac{5}{6}\)

You can surely see that you can rearrange this to read:

\(\displaystyle \frac{1}{x+1}+\frac{1}{x}-\frac{5}{6}=0\)

Now, you have three fractions. So what happens if you add/subtract them? You'll get a new fraction, which is equal to 0. When a fraction is equal to 0 what, if anything, can you say about the denominator? And what, if anything, can you say about the numerator? Can you see how to proceed from there?

The other three examples will follow the same basic process, so you should be able to give them a try as well. If you get stuck, that's okay, but please show us all of your work (even if you know it's wrong), so we can better assist you.
 
@ksdhart You are right i am having trouble rearranging the equation

@Denis could you please explain how you did it

Thank you guys for the help, later on i will post up my attempts

Denis showed the process step-by-step!!

Get a pencil and paper and start working on it and let us know exactly where you are stuck......
