X^3-8/x-2<br> simplify and I need an explanation please
Sergeu [11.5K]

Answer: x^2+2x+4

Step-by-step explanation:

The expression given in the exercise is:

 \frac{x^3-8}{x-2}

If you descompose the number 8 into its prime factors, you get that:

8=2*2*2=2^3

Therefore, you can rewrite the numerator of the expression as following:

=\frac{(x^3-2^3)}{(x-2)}

For this exercise you need to remember that for a  Difference of cubes:

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

Then, applying this, you get:

=\frac{(x-2)(x^2+2x+2^2)}{(x-2)}=\frac{(x-2)(x^2+2x+4)}{(x-2)}

Now, it is necessary to remember the following:

\frac{a}{a}=1

Knowing the above, you can say that:

\frac{(x-2)}{(x-2)}=1

Therefore applying this, you get that the simplified expression is:

=x^2+2x+4
