Step-by-step explanation:
we have to write the general form of a quadratic polynomial and a cubic polynomial in variable x.
Polynomial is an expression which consist of variables and coefficients connected with arithmetic operations like addition, subtraction, multiplication.
Quadratic Polynomial:
A polynomial of second-degree not larger than the degree 2.
Standard form of quadratic polynomial is
f(x)=ax^2+bx+cf(x)=ax
2
+bx+c
where a ≠ 0, and a, b, c are real or complex numbers.
Cubic Polynomial -
A cubic polynomial is a third-degree polynomial not larger than the degree 3.
Standard form of cubic polynomial is
p(x)=ax^3+bx^2+cx+dp(x)=ax
3
+bx
2
+cx+d
where a ≠ 0, and a,b,c and d are real or complex numbers.
Answer:
quadratic polynomial
ax²+bx+c=0
cubic polynomial
ax³+bx²+cx+d=0
