Step-by-step explanation:
We are given that there are:
Black helmets = 3
Red helments = 2
Let us start from the guy at the back. The guy at the back
can see the two helmets in front of him. If the two helmets in front of him are
red, then he can certainly say that his helmet is black since there are only 2
red helmets. Since that is not the case, then therefore he can either be black
or red. Therefore this also means that at least 1 of the 2 guys in front of him
has black helmet.
<span>Since the remaining two should have at least 1 black,
therefore the middle guy can see that the helmet in front of him is not red (so
1st guy is black). Because if the guy in front of him is red, then
he can know that he must be black since remember, at least one of the 2 front
guys must be black, but the middle guy cannot say that. Therefore the 1st
guy knows he has a black helmet.</span>

Step-by-step explanation:
Polynomials in one variable are algebraic expressions that consist of terms in the form a x n a x n where n is a non-negative (i.e. positive or zero) integer and a is a real number and is called the coefficient of the term. The degree of a polynomial in one variable is the largest exponent in the polynomial
