3b+2
The sub for b is 14

44

Step-by-step explanation:

I'm assuming you're meant to multiply so I did 3(14)+2 and it gave me 44 :)

so it should be 44

Step-by-step explanation:

So the sub for b is 14 so substitute the b to 14

Then 3(14) they are multiplying so multiply them should equal 42

Then add the 2 the answer should be 44

I hope that you understoood!

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.
