I know that 0 and 2 are roots but, how do you solve it algebraically? or what theorem or method do you use to solve it? (without using numerical or graphical methods)

Thanks

Show that the quadratic equation 3x^2 + p = (p+3)x has real roots for all values of p.

Show me every step please.

If energy is conserved and only degradated (entropy always grow)
I think the amount of energy in Big-Bang is the same that today perhaps there are a physics model that calculate it and how it degrades, isnt it?

1.ONE THING CAN NEVER REPRESENT ANOTHER THING IF THERE IS NO EQUIVALENCE IN THEM.

2. THE EQUIVALENCES OF THOSE YOU REPRESENT MUST BE IN WHAT YOU ARE.

certain a^(n)-b^(n) can be written as c^(2)-d^(2) like 7^(3)-4^(3) = 48^(2)-45^(2) (the numbers of the form of 4t+2 are not expressible as difference of two squares like 26=3^(3) - 1^(3) ). In such cases can we write the power as 2 in place of "n"?

According to Einstiens photoelectric theory, a single photon interacts with a single electron and transfers all its energy to the electron and loses all its identity.
However, according to Compton effect, a single X-Ray photon interacts with an electron and transfers only part of its energy and thus acquires a longer wavelenth.
Could anyone explain this ambiguity?

And don't say four, because I will flag you for abuse!!! Nobody will ever convince me that putting two and two together makes four things. Hold on, I have to make more banana muffins for the continental breakfast in the morning. Man, if there is one thing I hate more than trying to figure out the secrets in life, it's making Banana muffins! At least I don't have to make them with nuts today.
