Respuesta :

For this case what you must multiply the variable Z for each of the terms that are within the parenthesis and then do the corresponding subtraction.
 We have then that the product will be given by:
 Zx (X-4) =
 (Z * X) - (Z * 4)
 Rewriting:
 ZX-4Z
 Answer:
 the product is:
 ZX-4Z

The product of Zx (x-4) is:

Zx2 - 4Zx

Explanation and Solution:

Multiply Zx to each term of the expression inside the parenthesis

Zx multiplied by x is equal to Zx2     

Zx multiplied by -4 is equal to -4Zx,

Combining all the product, we have Zx2 - 4Zx as the answer.

 

PS. The x2 there is X squared
