What are all of the real roots of the following polynomial? f(x) = x4 - 13x2 + 36

A.
-3, -1, 1, and 3
B.
-3 and 3
C.
-3, -2, 2, and 3
D.
-2 and 2

m=-16

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road

it is c!

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
