Ok, so you probably know that; \( \tiny\\[0.5em] \) \(\color{#000000 }{ \displaystyle (x+a)^2= x^2+\color{red}{2a}x+a^2 }\) And, you have \(\color{#000000 }{ \displaystyle x^2+\color{red}{10}x+~\color{blue}{?} }\)

10 corresponds to "2a", so you can find the "a" based on that, and then refer to the form, \(\color{#000000 }{ \displaystyle x^2+2ax+a^2 }\) And, \(a^2\) is the number that you need to add.
