someone help me pls is due today and if the answer is correct I will give you brainliest and follow you backʕ ꈍᴥꈍʔ

b) 1/6

Step-by-step explanation:

You need to multiply the results from the question a) by 2.

1*2=2

6*2=12

=2/12

now simplify it

2/12

=1/6

Hope this  helps <3

step-by-step explanation:

it's is b

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
