Question

Find the product: (x + 2)( x − 2)

Answer 1

You simply multiply

Answer 2

Here: (x+2) times (x-2). You don't know?

Answer 3

Use the F.O.I.L Method.
Multiply: First, outside, inside, last
First: x*x= x^2
Outside: x*(-2)= -2x
Inside: 2*x= 2x
Last; 2*(-2)= -4
Then add all the terms: x^2 + (-2x) + 2x + (-4) = x^2-4

Answer 4

formula\[(a-b)(a+b) = a ^{2} - b ^{2}\]
\[(x-2)(x+2) = x ^{2}\]

Answer 5

sorry \[x ^{2} - 4 \]
