Multiply(x-2)(x+2)
I am totally lost!
just foil it out
take the first 2 terms from each parentheses and multiply them. then add the product of the inside and outside terms, then add the product of the last 2 terms
= x^2-2x+2x-4= x^2-4
To multiply the expression (x-2)(x+2), you can use the FOIL method.
FOIL stands for:
F - Multiply the First terms in each parentheses.
O - Multiply the Outer terms.
I - Multiply the Inner terms.
L - Multiply the Last terms.
Applying the FOIL method to (x-2)(x+2), we get:
F: x * x = x^2
O: x * 2 = 2x
I: -2 * x = -2x
L: -2 * 2 = -4
Now, you can combine the terms:
x^2 + 2x - 2x - 4
The like terms 2x and -2x cancel each other out, leaving us with:
x^2 - 4
So, the product of (x-2)(x+2) is x^2 - 4.
