%283x-7%29%282x%2B5%29 Start with the given expression.


Now let's FOIL the expression.


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


%28highlight%283x%29-7%29%28highlight%282x%29%2B5%29 Multiply the First terms:%283%2Ax%29%2A%282%2Ax%29=6%2Ax%5E2.


%28highlight%283x%29-7%29%282x%2Bhighlight%285%29%29 Multiply the Outer terms:%283%2Ax%29%2A%285%29=15%2Ax.


%283x%2Bhighlight%28-7%29%29%28highlight%282x%29%2B5%29 Multiply the Inner terms:%28-7%29%2A%282%2Ax%29=-14%2Ax.


%283x%2Bhighlight%28-7%29%29%282x%2Bhighlight%285%29%29 Multiply the Last terms:%28-7%29%2A%285%29=-35.


---------------------------------------------------
So we have the terms: 6%2Ax%5E2, 15%2Ax, -14%2Ax, -35


6%2Ax%5E2%2B15%2Ax-14%2Ax-35 Now add every term listed above to make a single expression.


6%2Ax%5E2%2Bx-35 Now combine like terms.


So %283x-7%29%282x%2B5%29 FOILs to 6%2Ax%5E2%2Bx-35.


In other words, %283x-7%29%282x%2B5%29=6%2Ax%5E2%2Bx-35.

This makes no sense, unless you are trying to evaluate if . You really need to:

1. Take more care in typing your problems.

2. Write out what it is that you want so that we don't have to guess.

3. Show the work that you have already done.

If you don't do those things, then we get the idea that you are just trying to get someone to do your work for you and that you have no real interest in learning mathematics. We are here to help you learn, not to provide a resource that allows you the luxury of not having to think or do work
