The following steps are used to rewrite the polynomial expression (x+4y+z)(x-7y).
Step 1: x(x-7y)+z(x-7y)
Step 2: x^2-7xy+4yx-28y^2+zx-7zy
Step 3: x^2-7xy+4xy-28y^2+xz-7yz
Step 4: x^2-3xy-28y^2+xz-7yz
Identify the property used in each of the steps:
Step 1:
Step 2:
Step 3:
Use Distributive, Commutative, Associative
