An equation with missing terms will have some of its terms removed.
The missing term that makes [tex]x^2 - 20[/tex] a perfect square is 100
The following step will calculate the missing term.
Represent the coefficient of x with k.
So, we have:
[tex]k = -20[/tex]
Divide both sides by 2
[tex]\frac k2 = -10[/tex]
Square both sides
[tex](\frac k2)^2 = (-10)^2[/tex]
[tex](\frac k2)^2 = 100[/tex]
This implies that, the missing term is 100
So, the complete equation is: [tex]x^2 -20x + 100[/tex]
