Typically, the way for multiplying squared binomials with a positive sign is by using this equation:
In this case, solve the equation:
The first part would be squaring the first term, which is
Second part is finding the product of the two terms given, then times two:
Third part is squaring the second term, which is
Combine it together and you would get
