Dengan menggunakan cara distributif 1. (x+3)(x+4) 2. (x+5)(x+2) 3. (x+2)(x-5) 4. (3p+2q)(p-5q) 5.(3p-4q)(2p+7q)

1. x (3+4) = (x+3) (x+4) = x^2+7x+12
2. x(5+2) = (x+5)(x+2) = x^2+7x+10
3. x(2-5) = (x+2)(x-5)= x^2-3x-10
4.(3p+2q)(p-5q)
=3p^2-15pq + 2pq -10q^2
= 3p^2-13pq-10q^2
5.(3p-4q)(2p+7q) = 6p^2+21pq-8pq-28q^2
= 6p^2 + 13pq-28q^2
