The products of the given expressions are:
Here, we have to find the product of the expressions given,
let's multiply them step by step:
First, apply the distributive property:
Now, add the results:
Product of (2x + 8) and
Combine like terms:
Product =
Product =
(x - 4)(x - 1)(20x + 4):
First, apply the distributive property:
Now, multiply the result with (20x + 4):
Combine like terms:
Product =
Product =
2(x + 4)(x - 4):
First, apply the distributive property:
2(x + 4) = 2x + 8
Now, multiply the result with (x - 4):
Combine like terms:
Product =
Product =
2x(x - 1):
Apply the distributive property:
2x * (-1) = -2x
Combine the terms:
Product =
2x(x + 4):
Apply the distributive property:
2x * 4 = 8x
Combine the terms:
Product =
So, the products of the given expressions are:

Answer:
x = pi/2 + 2 pi n x = pi + 2 pi n where n is an integer
x = 5pi /3 + 2 pi n
Step-by-step explanation:
8 cos^2 x + 4 cos x-4 = 0
Divide by 4
2 cos^2 x + cos x-1 = 0
Let u = cos x
2 u^2 +u -1 =0
Factor
(2u -1) ( u+1) = 0
Using the zero product property
2u-1 =0 u+1 =0
u = 1/2 u = -1
Substitute cosx for u
cos x = 1/2 cos x = -1
Take the inverse cos on each side
cos ^-1(cos x) = cos ^-1(1/2) cos ^-1( cos x) =cos ^-1( -1)
x = pi/2 + 2 pi n x = pi + 2 pi n where n is an integer
x = 5pi /3 + 2 pi n
