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)

a) x=4

10+2x+6=24
-2x. -2x
10+6=-2x+24
-24. -24
10+6-24=-2x
simplify
-8=-2x
divide both sides by -2
4=x

2. x=7


14+3x+5=40
-3x. -3x
14+5=40-3x
-40. -40
14+5-40=-3x
-21=-3x
divide both side by -3
7=x
