Best ResponseYou've already chosen the best response.0Let me ask you this, if you had \(\large\color{black}{ \displaystyle y=x^2+4x+\text{___} }\) then what number would you want in place of a blank to make this trinomial/expression a perfect square?

Best ResponseYou've already chosen the best response.0no, you wouldn't want a "1"..... you need this expression to factor into two equal parts.

Best ResponseYou've already chosen the best response.0well (x+2)(x+2) would give you the first term x² and second term 4x and a third term 4, is this right or not?
