Answer:

4n^3 -10n^2 +16n -10

Step-by-step explanation:

Use the distributive property to eliminate parentheses, then combine like terms.

= 2n(2n^2 -3n +5) -2(2n^2 -3n +5)

= 4n^3 -6n^2 +10n -4n^2 +6n -10

= 4n^3 +n^2(-6-4) +n(10+6) -10

= 4n^3 -10n^2 +16n -10

How do I solve the square root of 30?

Gre4nikov [31]

There is a way to work it out with a pencil and paper, but that's too complicated
to try and explain with only text, like we have here.

I don't usually recommend this for things that can be done easily on paper ...
but for square roots, your best bet is to use a calculator.

The square root of 30 does not come out even. It starts out 5.477225...
and it keeps going and never ends.

The negative of 5.477225... is also a square root of 30. Every number has
two square roots ... the positive and negative of the same number.

Slove for x: x+1/3=1/4

lana [24]

Hey!

To solve this problem, we must subtract one over three from both sides of the equation. This will give us x on its own.

Original Equation :
$x + \frac{1}{3} = \frac{1}{4}$

New Equation {Added Subtract $\frac{1}{3}$ to Both Sides} :
$x + \frac{1}{3} - \frac{1}{3} = \frac{1}{4} - \frac{1}{3}$

Solution {New Equation Solved} :
$x=- \frac{1}{12}$

So, this means that in the equation provided, $x=- \frac{1}{12}$ .

Hope this helps!
