The solution to the expression using the FOIL method is x⁴ - 6x² + 8
<h3>How to evaluate the expression using FOIL?</h3>
From the question, we have the following parameters that can be used in our computation:
(X2-2)(x2-4)
Rewrite the expression properly
So, we have
(x² -2)(x² - 4)
The FOIL method states that: First, Outside, Inside, and Last
Using the acronym as a guide, we have
(x² -2)(x² - 4)
Expand the expression
This gives
(x² -2)(x² - 4) = x²(x² - 4) -2(x² - 4)
Expand the brackets
So, we have the following representation
(x² -2)(x² - 4) = x⁴ - 4x² -2x² + 8
Collect the like terms
This gives
(x² -2)(x² - 4) = x⁴ - 4x² -2x² + 8
Lastly, we evaluate the like terms
(x² -2)(x² - 4) = x⁴ - 6x² + 8
Hence, the solution to the equation is x⁴ - 6x² + 8

Answer:
a -1
b 1
c 3
d 2
no
Step-by-step explanation:
The correct answer is x>0. This is because the circle is on 0, is hollow, and has an arrow that points right.
The rule for a reflection in the line y = x is (x,y) --> (y,x)
so (-6,-4) -----> (-4 , -6)
Answer
(-4 , -6)
