The Brayton cycle<span> is a thermodynamic </span>cycle<span> named after George Bailey </span>Brayton<span> that describes the workings of a constant pressure heat engine. The original </span>Brayton<span> engines used a piston compressor and piston expander, but more modern gas turbine engines and air breathing jet engines also follow the </span>Brayton cycle<span>.</span>
Answer:
Step-by-step explanation:
Let's examine the following general product of two binomials with variables x and y in different terms:
so we want the following to happen:
Notice as well that means that those two products must differ in just one unit so, one of them has to be negative, or three of them negative. Given that the product , then we can consider the case in which one of this (b or d) is the negative factor. So let's then assume that are positive.
We can then try combinations for such as:
Just by selecting the first one
we get that
and since
This quadratic equation give as one of its solutions the integer: d = -2, and consequently,
Now we have a good combination of parameters to render the factoring form of the original trinomial:
which makes our factorization:

I've posted solutions in the picture. Rather the ways to solve them. Check and find answers on your own.
Also, I've not solved the problem by differential calculus. You can, obviously, if you're interested. Use it for ease and for tougher equations.
