Question

State which of the following are polynomials and which are not? Give reasons.
1.2x³
2.1/x-1 (x≠0)
3.4z²+1/7
4.m²-√2m+2
5.p-²+1​

Answer 1

Answer:

1 no is polynomials 2.no is not polynomial because there is x in denominator.

Answer 2

Answer:

1.2x³,3.4z²+1/7 and 4.m²-root2m+2 are polynomial because the power of variable is positive integer....

whereas 2.1/x-1 and 5.p-²+1 are not polynomial because they dont have positive power of the variable....

mark as brainliest.......
