How would the expression x^3-8 be written using difference of cubes

ludmilkaskok [199]

we can use formula

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

we can compare

we get

a=x

b=2

now, we can plug that in formula

and we get

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

now, we can simplify it

$x^3-8=(x-2)(x^2+2x+4)$ ...........Answer

Eric wants to get an output of 0. Can he do this with each machine? If so, how? If not, why not?

natita [175]

Answer:

No, he can get an output of 0 with the second machine (function B) but he cannot get an output of 0 with the first machine (function A).

Explanation

The way each machine works is given by the expression (function) inside it.

1) Function A

To get an output of 0 with the function y = x² + 3, you must solve the equation x² + 3 = 0.

Since x² is zero or positive for any real number, x² + 3 will never be less than 3 (the minimum value of x² + 3 is 3). So, it is not possible to get an output of 0 with the first machine.

2) Function B

Solve $y=\sqrt{x}-2=0$
