I'd say what you would do is: You can either 1. Add 15 and 18 together and then divide by 2 OR 2. Since there is a 3 number difference between 15 an 18, just add 3 to 18

Write x^2 − 2x − 3 = 0 in the form (x − a)^2 = b, where a and b are integers.
Airida [17]
X²-2x-3 = 0     let's start by grouping the "x"s

(x² - 2x + [?])² - 3 = 0

so, we have a missing fellow there, in order to make the group, a perfect square trinomial, namely to "complete the square", hmmm so the tell-tale fellow is the middle term.

from a perfect square trinomial we know that the middle term is a product of 2 and the "term on the left" and the "term on the right", like 

\bf \begin{array}{cccccllllll}&#10; a^2& + &2 a b&+& b^2\\&#10;\downarrow && &&\downarrow \\&#10; a&& && b\\&#10;&\to &( a +  b)^2&\leftarrow &#10;\end{array}\qquad \qquad \quad &#10;\begin{array}{cccccllllll}&#10; a^2& - &2 a b&+& b^2\\&#10;\downarrow && &&\downarrow \\&#10; a&& && b\\&#10;&\to &( a -  b)^2&\leftarrow &#10;\end{array}

\bf \textit{therefore}\qquad 2(x)(\boxed{?})=\stackrel{middle~term}{2x}\implies \boxed{?}=\cfrac{2x}{2x}\implies \boxed{?}=1

aha!!  so our missing fellow is 1.

now, let's keep in mind that all we're doing is borrowing from our very good friend Mr Zero, 0.  So if we add 1², we also have to subtract 1².

(x² - 2x + 1² - 1²) - 3 = 0

(x² - 2x + 1) -1 -3 =0

(x - 1)² - 4 = 0

(x - 1)² = 4
