The following steps are used to rewrite the polynomial expression (x + 4y + 2)(x – 7y). Step 1: x(x - 7y) + 4y(x - 7y) + z(x – 7y)
Step 2: x2 - 7xy + 4yx - 28y2 + zx - 7zy
Step 3: x? - 7xy + 4xy - 28y2 + xz - 7yz
Step 4: x2 - 3xy - 28y2 + xz - 7yz
Identify the property used in each of the steps:
Step 1:
