The first one: 2x is equal to 12x/6. Wrong thing. You need to factorise the RHS and simplify the fraction im wrong for this one

Do you mean

2x = \dfrac{6}{x^2+6x+9}?

If so, just multiply both sides by the denominator and rearrange to set one side to 0. Then use the factor theorem to spot one solution and divide through to obtain a quadratic from which you can calculate the other roots.

Here's something to start with

2x (x^2+6x+9) = 2x^3+12x^2+18x = 6

How far have you got so far?
1) (x + 3) (x+3) ---- dont know what to do next
2) (x _ 6) (x _ 4) ----- dont know what to do next or how to format answer

Oh, right.

The first thing you need to know is that it is definitely not an equation if you meant a + sign and there is nothing to solve.

You can factorize the the top and bottom and cancel out common factors to simplify it.

Those aren't equations!

What are you supposed to be doing?

Can you post the entire question. As you have stated it, there is nothing to do as there is no equation to solve.
