Degree of the polynomial 4x4 + 0x3 + 0x5 + 5x + 7 is :
(A) 4
(B) 5
(C) 3
(D) 7
[A]
Solution: Polynomial:- It is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s)
Degree of a polynomial:- Degree of a polynomial is the highest power of the polynomial’s monomials with a non-zero coefficient.
Here given polynomial is 4x4 + 0x3 + 0x5 + 5x + 7 which can be write as 4x4 + 5x + 7
Here the highest power of the x-coefficient is 4 therefore the degree is 4.
