True. Polynomial means consisting of several terms. A<span>n expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variables.
For example:
f(x) = x3 + 2x 1/2
Since there are two parts to this equation, it is polynomial.

Standard form is the cord written normally. Like this, 1,563
A (real) square root of a number is always positive, so only (C) has no solutions.
Hope this helps i added an png
