Question

In the following algebraic expressions, which are polynomials in one variable, which
polynomials in two variables and which are not polynomials. Let us write them
-
(i) x2 + 3x + 2 (ii) x2 + y2 + a² (iii) y2 – 4ax (iv) x+y+2 (v) x + y + xºyº
5
(vi)x+x
X​
I NNED PROPER solution

Answer 1

Answer:

Answer is equation 1 and 6

1st equation=x2 + 3x + 2

it is linear equation in one variable as it only contains one variable x

and equation can be written as

p(x)=x2 + 3x + 2

2nd equation=x+x

it is linear equation in one variable as it only contains one variable x

and equation can be written as

p(x)=x+x

Step-by-step explanation:

Answer 2

Answer:

(i)3x

2

−2x+5 Polynomial is one variable

Here x is the only variable.

(ii)x

2

+

2

Polynomial is one variable

Here x is the only variable.

(iii)p

2

−3p+q Polynomial with two variables.

Here p&q are variables.

(iv)y+

y

2

Not a polynomial

∵y is having −ve power in second term.

(v)5

x

+x

5

Not a polynomial

∵x is having fractional power in first term.

(vi)x

100

+y

100

Polynomial with two variables.

Here x&y are variables.
