Question 159154: Hello:
I'm taking a college Intermediate Algebra Class and have not even thought about Algebra for about 4 years. My instructor has this online question that I do not understand with several multiple choice anwswers. None of which match the several attempts I have made.
Here's the question: "Multiply by definition exponents as needed"
x^2-6xy-y^2-4x^2y^3
|Note: there are no perenthese or operations other than the negative signs.|
The answers vary but have a general theme:
a) 24x^3y^4x^2y^5 (in despiration I chose this one as a guess, it's wrong)
b) 24x^3y^4x^2y^5 (Yeah I know it's the same)
c) 25x^3y^4x^2y^5
d) 26x^3y^4x^2y^5
I've tried everthing I can think of to do this problem. I just do not understand how to come up with one of these answers!
Could you please show me HOW to do this problem? And explaine each step? thanks very much.
Sylvia
Answer by checkley77(12844) (Show Source): You can put this solution on YOUR website!
x^2-6xy-y^2-4x^2y^3
None of these terms can be combined.
All your answer choices are products. Which by the way these answers are not properly complete.
Example:25x^3y^4x^2y^5=25x^5y^9
