Answer 2

$\large\underline{\sf{Solution-}}$

The degree of polynomial is defined as the highest power of variable.

So,

Answer :- 1 Degree is 1

Answer :- 2 Degree is 0

Answer :- 3 Degree is 5

Answer :- 4 Degree is 7

More to know :-

The degree of 0 is not defined even though its constant polynomial.

The polynomial of degree 1 is called linear polynomial

The polynomial of degree 2 is called quadratic polynomial

The polynomial of degree 3 is called cubic polynomial

The polynomial of degree 4 is called biquadratic polynomial

More Identities to Remember

(a + b)² = a² + 2ab + b²

(a - b)² = a² - 2ab + b²

a² - b² = (a + b)(a - b)

(a + b)² = (a - b)² + 4ab

(a - b)² = (a + b)² - 4ab

(a + b)² + (a - b)² = 2(a² + b²)

(a + b)³ = a³ + b³ + 3ab(a + b)

(a - b)³ = a³ - b³ - 3ab(a - b)
