1.2p(2pq+4)

=2p×2pq+2p×4

=4p²q+8p

we know that the product of a monomial and bionomial is always a bionomial

2.(p-2)(4p-5)

=p(4p-5)-2(4p-5)

=4p²-5p-8p+25

=4p²-13p+25

we know that product of two bionomial is always a trinomial.we used their grouping method and commutative property

product of bionomial, monomial and

trinomial

Step 1: Factor both the numerator and the denominator. ...
