%28x-6%29%28x-2%29 Start with the given expression


Now let's FOIL the expression



Remember, when you FOIL an expression, you follow this procedure:


%28highlight%28x%29-6%29%28highlight%28x%29-2%29 Multiply the First terms:%28x%29%2A%28x%29=x%5E2


%28highlight%28x%29-6%29%28x%2Bhighlight%28-2%29%29 Multiply the Outer terms:%28x%29%2A%28-2%29=-2x


%28x%2Bhighlight%28-6%29%29%28highlight%28x%29-2%29 Multiply the Inner terms:%28-6%29%2A%28x%29=-6x


%28x%2Bhighlight%28-6%29%29%28x%2Bhighlight%28-2%29%29 Multiply the Last terms:%28-6%29%2A%28-2%29=12


x%5E2-2x-6x%2B12 Now collect every term to make a single expression



x%5E2-8x%2B12 Now combine like terms


---------------------
Answer:
So %28x-6%29%28x-2%29 foils and simplifies to x%5E2-8x%2B12

In other words, %28x-6%29%28x-2%29=x%5E2-8x%2B12
