Factor this expression completely.<br><br> u^3 - v^3

Musya8 [376]

Completely factored form of u^3-v^3 is:

$(u-v)(u^2+uv+v^2)$

Step-by-step explanation:

Algebraic formulas are used to factorize the expression.

Given

$u^3 - v^3$

The formula involving cube with negative sign is:

$a^3-b^3 = (a-b)(a^2+ab+b^2)$

Using this formula:

$u^3-v^3 = (u)^3 - (v)^3\\= (u-v)(u^2+uv+v^2)$

Hence,

Completely factored form of u^3-v^3 is:

$(u-v)(u^2+uv+v^2)$

Tamia watched 1 2 of a movie in the morning, and she watched some more at night. By the end of the day, she still had 1 3 of the

KonstantinChe [14]

Answer: Tamiya watched $\dfrac16$ of the movie at night.

Step-by-step explanation:

Let x = part of movie watched at night.

Given : Tanya watched $\dfrac12$ of movie in the morning.

Part left to watch = $\dfrac13$

As per given, we have

$\dfrac12+x+\dfrac13=1\\\\\Rightarrow\ x=1-\dfrac13-\dfrac12\\\\\Rightarrow\ x=\dfrac{6-2-3}{6}\\\\\Rightarrow\ x=\dfrac16$

Hence, Tamiya watched $\dfrac16$ of the movie at night.
