Question

.
19. Write the general form of the following:
a) Linear polynomial
b) Cubic polynomial​

Answer 1

Answer:

a x 3 + b x 2 + c x + d = 0 ax^3+bx^2+cx+d=0

Step-by-step explanation:

A cubic equation is an equation which can be represented in the form a x 3 + b x 2 + c x + d = 0 ax^3+bx^2+cx+d=0 ax3+bx2+cx+d=0, where a , b , c , d a,b,c,d a,b,c,d are complex numbers and a is non-zero. By the fundamental theorem of algebra, cubic equation always has 3 roots, some of which might be equal.
