Need help with a maths problem

[bckc]

First of all, you need simplify the equation:

x^2 + 3x + 2 = x^2 + ax + 2x + 2a

Then, we bring the variable to one side and the numerical values on the other side by transposing them:

x^2 + 3x - x^2 - ax -2x - 2a = -2

By simplifying further, we get:

x - ax = -2

-x + ax = 2

Now we try to bring x to right hand side:

a = (2 + x)/x

This is the solution for a in terms of x. If you have the value of x, then you can find the value of a as well.


Hope this helps.

Allthough this answer wos incorrect it still made my brain hurt xD I've never been great at maths.

I was in Algebra 1 but I decided that I was more interested in the Calculators (TI89+ or something like that)
So I got taken out.

Is it just me or is this hard?

It is sort of hard.
Not that hard though.. I just couldn't concentrate ;)

I find it as easy as addition and multiplication, it's all it really is. (+/-, divide/multiply)

If you know the basic concepts like BODMAS and arithmetic, then it isn't as hard as it seems.

Well, I'm only in 8th grade. So we haven't started this yet.

"BEDMAS"? You mean

"BEDMAS"? You mean

There are many variations of the rule: BEDMAS, BIDMAS, BODMAS, BERDMAS, PERDMAS, and BPODMAS are some of them. I was taught BODMAS. The "O" stands for Order instead of Exponentiation.

Well it is the "Exponents" after the "Brackets" so I find it easier to remember that way. Never knew there were other variations.
