8z- 125​

Answer 1

Answer:

Factoring difference of cubes (

a 3 − b 3 ):  ( a − b )( a 2 + a b + b 2 )

Here,  

a is  2 x because the cube root of 8 is 2 and the cube root of  

x 3 is  x ,  b is 5 because the cube root of 125 is 5.  

Plug the numbers in:

( 2 x − 5) ( 2 x ) (2 + 2x ⋅ 5 + 5 2 )

( 2 x − 5 ) ( 2 2 x 2 + 10 x + 25 )

( 2 x − 5 ) ( 4 x 2 + 10 x + 25 )

Answer 2

Answer:

(2 - 5)z (2^2 + 2 × 5 + 5^2)

Step-by-step explanation:

2^3 z - 5^3

this results in the form of

a^3 - b^3= (a-b) (A2+b2+ab)

so on factorising we get,

(2 - 5)z (2^2 + 2 × 5 + 5^2)
