Which of the following is the complete list of roots for the polynomial function f (x) = (x2 + 6x + 8) (x2 + 6x + 13)?
Natali5045456 [20]

Answer:

-2, -4, -3 + 2i, -3-2i

Step-by-step explanation:

Equaling the function to zero we have:

(x ^ 2 + 6x + 8) (x ^ 2 + 6x + 13) = 0  

For the first parenthesis we have:

(x ^ 2 + 6x + 8) = 0\\(x + 4) (x + 2) = 0  

Therefore the roots are:

x = - 4\\x = - 2  

For the second parenthesis we have:

(x ^ 2 + 6x + 13) = 0  

By completing squares we have:

x ^ 2 + 6x = -13  

x ^ 2 + 6x + (\frac{6}{2}) ^ 2 = -13 + (\frac{6}{2}) ^ 2\\x ^ 2 + 6x + 9 = -13 + 9\\(x + 3) ^ 2 = - 4\\x + 3 = +/- \sqrt{-4}    

Therefore the roots are:

x = -3 + 2i\\x = -3 - 2i  

Hope this was helpful

Marcus drew a line from point Y to point W in the rectangle shown below. He created two identical triangles. Classfy the triangl
telo118 [61]
When you draw a diagonal line from Y to W, you will create two congruent triangles.

Each of these triangles will have three sides of different lengths, making them scalene triangles.

In each of these triangles, there will be one 90° angle, right angle, and two acute angles (less than 90°). This would classify these triangles as right triangles based on the angles.

Both triangles are right, scalene triangles.
