you can use it house or at the mall or anywhere
Pharmacists and the makers of drugs use polynomial division. They use this type of division to help create formulas to make sure that the proper amount of drug is being distributed to the patients depending on the variables involved.
They don't. At least, not for their nursing work.
When do you use long division?You use long division when the number you are dividing is too big to do in your head or use short division.
If the cubic polynomial you are given does not have an obvious factorization, then you must use synthetic division. I'm sure wikipedia can tell you all about that.
to multiplya polynomial by a monomial,use the distributive property and then combine like terms.
Arrange terms in both in decreasing order based on the exponents. Use the algorith for long division. This is just like long division. Step 1. Divide 1st term into 1st term, (place answer above division line). Step 2. Multiply that answer by all terms in the divisor, (place this result below the polynomial inside the division bar) Step 3. Subtract like terms (answer goes down 1 line) and bring down another term to continue. Repeat: Step 1. Divide 1st term into new 1st term. etc
As with most advanced math, if your "real life" involves engineering work, you will use such math; otherwise, you will hardly have anything to do, in this case, with polynomial functions.
You use long division.
