Please mark as brainlist

Step-by-step explanation:

estion 1:

State whether the given algebraic expressions are polynomials? Justify.

(i) y +

1

y

(ii) 2 - 5

√

x

(iii) x2 + 7x + 9 (iv) 2m-2 + 7m - 5 (v) 10

ANSWER:

In an algebraic expression, if the powers of the variables are whole numbers then the algebraic expression is a polynomial.

(i)

y+

1

y

=y+y-1

Here, one of the powers of y is −1, which is not a whole number. So, y +

1

y

is not a polynomial

Answer 2

Answer:

polynomial , because the exponent of the variable of 8 or 8x0 is 0 which is a whole number . (iii) Not polynomial ,because the exponent of the variable of 1-√5xor1-√5x12)is 12 which is not whole number. ... (viii) Not polynomial , because the exponent of the variable of 12xor12x-1 is -1 which is not a whole number.
