Question

State true or false

a.) x⁵-5x⁴-2 is a polynomial in degree 5

b.)3ab+b+a is a polynomial in two variables.​

if true or false then how
show the solution​

Answer 1

Answer:

both are true because reason for the 1st it has the highest degree which 5 and in second part it has two variables of course there are these are a and b

Answer 2

Answer :-

a) True

b) True

Solution :-

a) Degree is the highest power of variable in the polynomial.

In x⁵ - 5x⁴ - 2 the highest power of x is 5.

So the degree is 5

Hence, the statement is true.

b) 3ab + b + a has 2 variable that are a and b.

So the polynomial has 2 variables

Hence, this is also true.
