Question
Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement.$x^{2}+4=(x+2)(x+2)$
Step 1
FOIL stands for First, Outer, Inner, Last. This means we multiply the first terms in each binomial, then the outer terms, then the inner terms, and finally the last terms. So, $(x+2)(x+2)$ becomes $x^{2}+2x+2x+4$. Show more…
