Question

which of the following expressions are polynomials in one variable and which are not? give reason for your answer. 3x²-2x+5,x²+root 2,root 2x³+5,2x³+5,payi/2x³+x,-2/3x³,2x²+5,x-1​

Answer 1

Step-by-step explanation:

(i) In the above expression 3x sq-2x+5 the variable is x.so,it is a one variable expression.

(ii) x sq +√2 the variable is x.so,it is a one variable expression.

(iii) The co- efficient of x cube is 2.

(iv) The co-efficient of of x cube is -2/3

(v)0x cube+2x sq+5

0+2x sq+5=2x sq+5

The co- efficient of x cube is 0.

(vi) The degree of the polynomial is 1.

so it is a linear polynomial.
