Question

Which is the algebraic expression is a polynomial with a degree of 2​

Answer 1

Explanation:

A polynomial is something off the form ax^n+bx^(n-1)+cx^(n-2)+.........+x

so a 2nd degree polynomial is the one in which highest degree of the polynomial is 2 i-e, in above generalization n=2

so in single variable following are the polynomials of degree 2

an^2+bx+c

an^2+c in case b=0

an^2+bx, in case c=0

in double variable case following are the polynomials with degree 2

axy+bx+cy
