(g 2 + 4)(4g 2 + 8g – 9)


I am sure you mean (g^2 + 4)(4g^2 + 8g - 9).

Use the Distributive Property: first multiply g^2 by each term in 4g^2 + 8g - 9, then multiply 4 by each term in 4g^2 + 8g - 9.

Then add like terms.

To learn how to multiply polynomials, try some online lessons (http://www.google.com/search?hl=en&q=multiplying+polynomials&btnG=Google+Search). :wink:

Once you have studied the necessary background terms and techniques, please attempt the exercise. If you get stuck, you will then be able to reply with a clear listing of your work and reasoning so far. Once we "see" where you're having trouble, we'll be able to provide specific helps to get you un-stuck.

Thank you! :D

You have posted similar problems - and the tutors did all the work for you.

Apparently you did not learn anything from this problem and the website referenced here - thus you did not show any work for those problem. Please show us that you are making an effort to learn - we are not assisting you in cheating yourself out-of learning. These skills will be needed later. If you don't learn to swim now - you'll sink later.

Please show your work, indicating exactly where you are stuck - so that we know where to begin to help you.

That d'you think, Subhotosh ?

Simplify: (x^2 + 2)(2x^2 + 3x -5)

The multiplication: 2x^4 + 3x^3 - x^2 + 6x - 10

Is that "simplifying"?!

Seems the statement should be "complicate the expression" :wink:

At least, call it:
Expand: (x^2 + 2)(2x^2 + 3x -5)

Addition/Subtraction simpler than multiplication ???!!! :shock:
