The equation has no solutions.
If, after a correct and legit manipulation, an equation turns into a false statement, than the original equation had no solutions.
It's easy to build an example: start with the equation
It is clear that this equation has no solutions: we can't get the same result by adding 1 and 2 to the same number! In fact, we can subtract x from both sides (which is a totally legit operation) and get
Which is a false statement, reflecting the fact that the equation had no solutions to begin with.
Answer:
a x^2/2 is a polynomial because the power of x is 2 which is a positive whole number but 2/x^2 is not a polynomial because the power of x is -2 which is negative whole number.
b.in
the power if x will be
which is not a whole number so it is not a polynomial.
but in
the power if x is a positive whole number.so it is a polynomial.
c.the greatest power of variable of the term is called degree of polynomial
