Question

Which one is not a polynomial a. 4y 2 – 3y+3 b. Y+ c. y 2 + y – 3 d. X 3 - 1

Answer 1

Step-by-step explanation:

Given: Four expressions

a. 4y² – 3y+3

b. Y+c

c. y² + y – 3

d. X³ - 1

To find:Which one is not a polynomial

Solution:A polynomial is an expression in a variable having positive integer powers of that variable.

Let us discuss one by one:

$a)4 {y}^{2} - 3y + 3$

it is a polynomial in y.It's degree is 2.

check points: y have positive integer powers

$b)y + c$

it is a polynomial in y.It's degree is 1,known as linear polynomial.

check points: y have positive integer powers

$c) {y}^{2} + y - 3$

it is a polynomial in y.It's degree is 2.

check points: y have positive integer powers

$d) {x}^{3} - 1$

it is a polynomial in x.It's degree is 3.

check points: y have positive integer powers

Hope it helps you.
