$$P (x) = (2+3x)^3$$

anonymous · Answer

Same concept. Rearrange for x.

anonymous · Answer

I am just terrible at it :/ sorry.

There are rules you can use to rearrange equations. An equation is where you have "some stuff" = "some other stuff". both sides are equal. So, you need to follow some rules so that they both stay equal.

anonymous · Answer

To rearrange the equation above, you need to know only a few rules. For example, x^2=y. Then x = sqrt(y). x^3 = y then x = cubed root of y. etc...

You can add any number to each side (so long as you add it to both sides). You can also multiply each side by any number (so long as you multiply both sides).

By combining those things, you can rearrange so that you get x on its own.

Firstly start by getting ride of the cube power on the right... so you take the cubed root of both sides... then keep going.

Gradually you will get closer to having x on its own. Don't worry about how crazy the left side looks...
