Answer:
x² - 16
Step by step:
using (a - b)( a+ b)= a²- b²
simplify the product
evaluate the power
x²-16
Step-by-step explanation:
You can use two methods in solving this: The FOIL method and Special Products in Difference of Two Squares.
FOIL Method:
Multiply the First terms (x•x), Outer terms (x• -4), Inner terms (4•x), Last terms (4• -4) then you'll get this answer
=x²-4x+4x-16
Now add like terms
= x²-16 here's the answer
Let's try solving Special Products (which should be used)
Just square the 1st term (x) and last term (4) leaving the minus sign (-) as the operation like so:
= (x)² - (4)²
= x² - 16 we had the same answer
So I want to know in the comments section which is much easier The FOIL method and The Special Products
Hope this could help:))))
