Ok so this one can be factored like this first:
3(6x^2-5x-6)
Then you have to factor like you normally would for a complex one:
(Put aside the 3 for now just know it's there to make the problem easier)
6x^2-9x+4x-6
3x(2x-3)+2(2x-3)
Adding the 3 put aside now

3(3x+2)(2x-3) is the final factored answer

PleaseeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeSimplify -2^3

Answer:

Therefore,

$(-2)^{3}=-8$

Step-by-step explanation:

Simplify

-2^3

$(-2)^{3}$

It is read as negative 2 raised to the power three,

also it is the cube of negative 2

we know that $a^{3}$ given as

$a^{3}=a\times a\times a$

so for negative a i.e -a

$(-a)^{3}=-a\times -a\times -a$

substituting a = 2 we get

$(-2)^{3}=-2\times -2\times -2$

negative sign multiplied by odd number of times then the sign remains negative.

Therefore,

$(-2)^{3}=-8$
