I think you need to explain more for one to answer it.
Please give more details and I'll try to help (if this is meant to be a question)
First observe that x=-1 is a root of the equation. Use long division to divide x^3-3x^2+x+5 by x+1, we find that (x^3-3x^2+x+5)/(x+1)=(x^2-4x+5). Now we need to find the roots of x^2-4x+5.
x^2-4x+5=0,
x^2-4x+4=-1,
(x-2)^2=i,
x-2=i or -1,
x=2+i or 2-i.
The three roots are 2+i, 2-i, -1.
Answer:

Answer:
The m∠ U is 72°.
Step-by-step explanation:
Given:

To find :

Solution:
The sum of the measures of the interior angles of a polygon with 'n' sides is given as

Here we have n = 5 on substituting the values we get

Therefore,
m∠ U is 72°.
Answer:

Step-by-step explanation:


Subtract 9 from both sides:


Add 6x to both sides:


Divide both sides by -4:
