513 +-3918

-3405

Step-by-step explanation:

So first you subtract 513 from 3918.

This way, you are doing basically an additive inverse.

So you so that and you get the answer. Because you are adding a negative, you are taking away from the positive and going into the negative, which would give you -3,405.

Hope this helped you a little!!^_^

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.
