Question

What is the value of
4q^ 3-4q

Answer 1

4q^3 - 4q

= 4q(q^2  - 1)

= 4q [(q)^2 - 1^2]

by identity a^2 -b^2

here,

=4q *[(q+1) (q-1)]

=4p(q+1)(q-1)

i hope this will help you

Answer 2

Hlo friend.. Cutiepie Here..

Here is ur answer :

First we have to take common factor,

4q³ - 4q

4q ( q² - 1)

Now by using identity,

a² - b² = ( a + b) ( a - b)

4q [ (q)² - (1)²]

4q ( q + 1 ) ( q - 1 )
