Its math.... I need it to be processed in english step by step..

Hey Dwight. This kind of thing looks messy, but it becomes much more simple when you break it down.

Multiplying two polynomials means multiplying each term in the first expression by each term in the second expression, and then adding them all together. Let's take it just a little bit at a time.

First we will multiply A by the second expression, but we'll do this one term at a time.

A * A

A * -3AB = -3A

A * -b

Now we need to add these all together. Using the same rules, we come up with A

A * A

^{3 }= A^{4}Remember that multiplying similar variables is the same as adding exponents. A^{1 }+ A^{3 }= A^{4}because 1 + 3 = 4A * -3AB = -3A

^{2}B Multiplying different variables is the same as multiplying a variable and a constant. 5 * x is as simple as that expression can get, so it just stays at 5x (we take out the multiplication symbol to make it easier to read. It's still there though).A * -b

^{2 }= -AB^{2}This one is the same thing as the second one. Remember that one negative in an expression will make the entire expression negative, which is why we can move the - symbol to the front.Now we need to add these all together. Using the same rules, we come up with A

^{4 }- 3A^{2}B - AB^{2}Now we are going to do the same thing with the second part of our first expression. We've already done something similar, so this will be really easy.

B * A

B * -3AB = -3AB

B * A

^{3}= A^{3}BB * -3AB = -3AB

^{2}B * -B

^{2 }= -B^{3}Adding those together gives us A

^{3}B - 3AB^{2 }- 3B^{3}And we are going to add this to the earlier part of our answer, for a complete answer of

A

^{4 }+ A^{3}B - 3A^{2}B - 4AB^{2 }- B^{3}
