For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
By definition, if two lines are perpendicular then the product of their slopes is -1.
We have the following equation of the line:

Then 
We find 

Thus, the perpendicular line will be of the form:

We substitute the given point and find "b":


Finally, the equation is of the form:

Answer:
-17.964
Step-by-step explanation:
We can solve it like:
3x^3+3x^2+x+1= (3x^3+3x^2)+(x+1)=
3x^2(x+1)+(x+1)=
= (x+1)(3x^2+1)
