Dividing by something is the same as multiplying by that something's reciprocal.

i have tried that but still the power is larger than a quadratic, so i wasnt able to solve it

Reduce the $$4-2x$$ terms and also with the left over $$4-2x$$ you can factor out a common term of 2.

Factor our a common term of 3 in $$3-3x$$ and keep going from there.

Another tip is to square root both sides to get rid of the even powers larger than 2 after you've done all that.

did factor out the 3 it becomes 27, i think
and canceled some of the 4-2x , as you suggested

but the main problem for me is still so much x,
cant really isolate it, because i tried expanding it
and i get like x^1 , x^2, x^3, X^4...
and do not know how to solve those
