Question

1. Which of the following expression
are polynomials in one variable
and which are not ? State
reasons for your answers
c/ 4x²-3x+7
c/3√t+t√2
/ y+2by y
​

Answer 1

Answer:

》4x²-3x+7

Here power is 2,1 and 0

therefore, it is a polynomial

since there is only one variable x,

it is polynomial in one variable.

$3 \sqrt{t } + t \sqrt{2}$

Polynomial is a term given to an expression

which have coefficients as well as variables with power not negative and is whole nos therefore this equation is not a polynomial as 3 root t has power 1/2 and it is not a whole nos.

》y+2/y

Here y has power 1 and in 2/y y has power

and -1 is not a whole nos. therefore this equation is not a polynomial .
