b. (x + 2)(x + 3)
c. (p + q) (p + q)
d. (12x³ +18x²)6x²

Answer 1

Answer:

Explanation:

We can use the highly useful mnemonic FOIL (Firsts, Outsides, Insides, Lasts). This is the order we multiply in. We get

Multiply the first terms:

x⋅x=x2

Multiply the outside terms:

x⋅−3=−3x

Multiply the inside terms:

−2⋅x=−2x

Multiply the last terms:

−2⋅−3=6

Putting it all together, we get

x2−3x−2x+6, or x2−5x+6

Hope this helps!
