Algebra - Binomial expansions with like and unlike terms

Binomial expansions with like and unlike terms

When binomial expressions have like terms, multiplying the terms from the
brackets will give four new terms. The example shown is:

(_a_ +_ b_)(_c_ + _d_) = _ac_ + _ad_ + bc + _bd_

When binomial expressions have like terms, multiplying the terms from the
brackets will give at four new terms, at first. However, the two middle
terms may be combined, and the resulting expression would have three terms.
The example shown is:

(x + 3)(x - 5) = x - 2 -15
