Answer 1

Answer:

1) polynomial of degree 2

2) 2

3)x^20+2

4)3

5)quadratic

Answer 2

ANswer :

1) x²-2x + 1 is a polynomial in:

→ One Variable

Reason :- x²- 2x + 1 can be written as x² - 2x¹ + 1x⁰. Hence, we can see that x is the only variable having powers as whole numbers: 2, 1 and 0.

2) The coefficient of x² in 3x³+ 2x²- x + 1 is:

→ 2

Reason :- The coefficient of x² in equation 3x³ + 2x² - x + 1 is the multiple of x².

3) A binomial of degree 20 in the following is:

→ x²⁰ +1

Reason :- A polynomial having two terms and the highest degree 20 is called a binomial of degree 20.

4) The degree of 4x³-12x²+ 3x + 9 is

→ 3

Reason :- The degree is the highest power of a variable in an equation.

5) x³ – x is ________ polynomial.

→ Quadratic

Reason :- A polynomial of degree two is known as quadratic polynomial.
