Answer 1

Answer:

degree of the expression is 3

Step-by-step explanation:

The degree of the polynomial is the highest value of the exponent in the polynomial.

Expansion of a+b the hole square is a ²+2ab +b²

Answer 2

a. Degree is the highest power on a variable of a given expression,

Here, highest power is $x^{3}$

So, degree of this polynomial is 3

b. Using, algebraic identity, we can expand $(a+b)^{2}$, i.e -

$(a+b)^{2\\}\\a^{2} +b^{2} \\(a+b) (a-b)\\a^{2} +ab+ba+b^{2} \\\\a^{2} +2ab+b^{2}$

∴ (a+b)² = a²+2ab+b²
