Expand the expression (x8)(x+2)(x-8)(x+2) using the FOIL method.

STEP 1

Assumptions
1. We are given a binomial expression (x8)(x+2)(x-8)(x+2).
2. We need to use the FOIL method to expand this expression.
3. FOIL stands for First, Outer, Inner, Last, which refers to a method for multiplying two binomials.
4. The result will be a quadratic expression.

STEP 2

First, we multiply the First terms in each binomial.
First=xxFirst = x \cdot x

STEP 3

Calculate the product of the First terms.
First=x2First = x^2

STEP 4

Next, we multiply the Outer terms in each binomial.
Outer=x2Outer = x \cdot 2

STEP 5

Calculate the product of the Outer terms.
Outer=2xOuter = 2x

STEP 6

Now, we multiply the Inner terms in each binomial.
Inner=8xInner = -8 \cdot x

STEP 7

Calculate the product of the Inner terms.
Inner=8xInner = -8x

STEP 8

Finally, we multiply the Last terms in each binomial.
Last=82Last = -8 \cdot 2

STEP 9

Calculate the product of the Last terms.
Last=16Last = -16

STEP 10

Now, we combine all the products from the First, Outer, Inner, and Last steps to get the expanded form.
Expandedform=First+Outer+Inner+LastExpanded\, form = First + Outer + Inner + Last

STEP 11

Substitute the calculated products into the expanded form.
Expandedform=x2+2x8x16Expanded\, form = x^2 + 2x - 8x - 16

STEP 12

Combine like terms in the expanded form to simplify the expression.
Expandedform=x2+(2x8x)16Expanded\, form = x^2 + (2x - 8x) - 16

STEP 13

Simplify the like terms.
Expandedform=x26x16Expanded\, form = x^2 - 6x - 16
The expanded form of (x8)(x+2)(x-8)(x+2) using the FOIL method is x26x16x^2 - 6x - 16.
