I'd like to know what is a polynomial( the definition and an explication)? And is 7x a polynomial? and why?
First a couple of examples.
7 x - 5 and
x 3 - 5x 2 + 2
x + 3/x
an xn + an-1 xn-1 + ... + a2 x2 + a1 x + a0
Where n is an integer and an, an-1,...,a0 are numbers.
For example if n = 1, a1 = 7 and a0 = 0 then you get the expression 7x, so 7x is a polynomial.I hope this helps,
