In life terms it is metabolism but you want the term decomposition for chemical reaction. There are synthesis, decomposition, single replacement, and double replacement. Decomposition is the reverse of synthesis.

I hope the question refers to a particular decomposition. Some decompositions are very exothermic and/or exergonic. The explosive decomposition of nitroglycerin and TNT are examples of that. The same applies to synthesis reactions. Not all of them are exothermic.

The 7r term disappears in the factoring process. The second order polynomials in the numerator and denominator were both factored by Damon. You may need to review the factoring process; it is an important part of algebra. You can multiply the two monomial factors back together...

Math: Factoring
First find one root by trial and error. Call it a. Then divide (x-a) into the cubic using long division to get a quadratic equation. Get the roots of that by the usual method. For the equation -x^3+2x^2+4x-8, one of the roots is x=2. Divide (x-2) into -x^3+2x^2+4x-8, and you ...

You can factor it out like this. 120 / \ 2 60 / \ 2 30 / \ 2 15 / \ 3 5 by factoring out to just prime number you can see which numbers 120 is divisible by. Also is you multiply some of these factors together you can find other factors. oh and don't forget the number 1 and the...
