Polynomials are algebraic expressions that
consist of variables and coefficients. Variables
are also sometimes called indeterminates. We
can perform arithmetic operations such as
addition, subtraction, multiplication, and also
positive integer exponents for polynomial
expressions but not division by variable.

Rules
There are a few rules as to what polynomials
cannot contain:
Polynomials cannot contain division by a variable.
...
Polynomials cannot contain negative exponents.
...
Polynomials cannot contain fractional exponents.
...
Polynomials cannot contain radicals. ...
Example: Figure out the degree of
7x2y2+5y2x+4x2.

Equation
A polynomial equation in two variables is an
equation of the form p(x, y) = q(x, y) where
both p(x, y) and q(x, y) are polynomials in two
variables. Examples. xy +2= y2 - 3x - 4 (xy
+ 2 is a quadratic polynomial. So is y2 - 3x 4.)
Archimedes. Famous
mathematician: Archimedes. Archimed
es was a Greek Scientist, a great
mathematician, and a Physician. He
also worked his entire life ...
Archimedes developed the
mathematical foundations underlying
the advantage of basic machines: lever,
screw and compound pulley.
Archimedes of Syracuse was a
Greek mathematician,
physicist, engineer,
astronomer, and inventor from
the ancient city of Syracuse in
Sicily. Although few details of
his life are known, he is
regarded as one of the leading
scientists in classical antiquity
