Question

. Find and correct the error in : z(5z² - 80 ) = 5z³ - 80

Answer 1

Answer:

z (5z² - 80) = 5z³ - 80z

Step-by-step explanation:

Since z is outside the bracket, we need to multiply every term inside the bracket with z (distributive property). So, the error is that z has been multiplied with 5z², but not with 80.
