SOLUTION: I need help with this problem it says to simplify each product and then write in standard form. (x-2)(2x*2x+x+4) I mostly just dont understand what to do and what it all means so

Question 80180: I need help with this problem it says to simplify each product and then write in standard form. (x-2)(2x*2x+x+4) I mostly just dont understand what to do and what it all means so if someone could help me it would be highly thankful.

You can put this solution on YOUR website!
%28x-2%29%282x%2A2x%2Bx%2B4%29+=+%28x-2%29%284%2Ax%5E2%2Bx%2B4%29 now you want to multiply x by all of the values in second () and then multiply -2 by all the values in second ()
now you want to combine alike terms, you can only combine (add or subtract) them if they have the same unknows (in this case you have only one unknown, it is x), also unknowns have to be raised to the same power ie you can add x%5E2 and2%2Ax%5E2 but you can't add x%5E2 and 3%2Ax
so your result is
4%2Ax%5E3-7%2Ax%5E2%2B2%2Ax-8
i'm not too sure about the standard form, usually you would write your answer in descending order of the power of variables/unknowns
i hope this helps
