Use the distributive property to expand the expression. 5x2 β (6x β 4y) + 9z
Accepted Solution
A:
You start with the parenthesis so ou have to distribute the minus. It gives you 5x2 - 6x + 4y + 9z Then you can do the first multiplication (Iβm assuming itβs not the letter x by the 5) So you end up with 10 - 6x + 4y + 9z Hope that helps :)
