2 times the product of the terms.
(a + b)² = a² + 2ab + b²
(a + b)² - (a² + b²) = a² + 2ab + b² - a² - b² = 2ab

Let's take a binomial: x + 2
The square of this binomial would be (x + 2)^2, and
the sum of the terms of the binomial squared would mean you have to expand it out.
(x + 2)^2 = (x + 2)(x + 2) = x^2 + 2x + 2x + 4 = x^2 + 4x + 4

this does not ingredient. on your application instructions it says to work out if the words have diverse warning signs. they have an identical sign. +v² and +sixteen. this won't be factored because of the fact the indications are an identical. in the event that they have been diverse, it may be the edition of proper squares. do no longer make the errors of attempting to ingredient it into (v + 4)(v + 4). in case you multiply it our you get v² + 8v + sixteen. that may no longer what you began with. good success

Even using simple terms
(a^2 + b^2) =/= (a + b)^2
(a + b)^2 = a^2 + 2ab + b^2

simple lets take a generic binomial (a-b)
(a-b)^2=a^2-ab+b^2
(a+b)^2=a^2+ab+b^2

It depends on who is asking you the question. Some teachers for example like it one way, while another teacher might not.

One is (x+y)^2 = x^2 + 2xy + y^2.
The other is x^2 + y^2.
