Question

Find zeros of the polynomial of the following.

(a)x3

– 4 x​

Answer 1

Answer:

2,-2,0will be the answers

Answer 2

Answer:

0,2,-2

Step-by-step explanation:

The factors of 3rd-degree term x³, shares same factor with -4x.

The same factor is x. Therefore, we can factorize the given polynomial.

x³ - 4x = x(x²) - 4x = x(x² - 4)

The zero of x is 0, while the zeros of x²-4 is +2 and -2.

Therefore, the zeros are 0, 2, -2.
