Question

Factorize the polynomial : 1. x² - 16 2. 3x³-9

Answer 1

Answer:

1st answer is 4 and 2nd one is 3 underrrot3

Step-by-step explanation:

1.

x^2-16=0

x^2=+16

x= under root16

x=4

2.

3x^3-9=0

3x^3=9

x^3=9/3

x^3=3

x=3 under root3

Answer 2

Answer:

Hence by the factorisation of x^2- 16, we get x=-4 and 4, by the factorisation of 3x^3, we get x= cube root of 3. Hope this helps you. If it helps you, mark me as Brainlist.
