Question

what is linear , quadratic and cubic polynomials ?​

Answer 1

Answer:

A polynomial whose degree is 3 is termed as a cubic polynomial. Hence any cubic polynomial in one variable x is of the form ax3 + bx2 + cx + d, where a, b, c and d are constants and a ≠ 0 (because if a = 0, then the polynomial will be 0 + bx2 + cx + d = bx2 + cx + d which is a quadratic polynomial of degree 2).

Answer 2

Answer:

• Linear polynomials. A linear polynomial is any polynomial defined by an equation of the form. p(x) = ax + b. where a and b are real numbers and a 6= 0. For example, p(x)=3x 7

• A cubic polynomial, in general, will be of the form. p(x):ax3+bx2+cx+d,a≠0. Once again, the constraint that a should not be equal to 0 is required because if a is 0, then this becomes a quadratic rather than a cubic polynomial

• In algebra, a quadratic function, a quadratic polynomial, a polynomial of degree 2, or simply a quadratic, is a polynomial function with one or more variables in which the highest-degree term is of the second degree
