Answer:
<em>The expression is; x^2 – 4c + 4</em>
Step-by-step explanation:
For the expression to be a perfect square, let us say the constant term should be assigned as ⇒ c;
This creates of following expression;
x^2 - 4x + c
In order to be a perfect square, the discriminant needs to be zero
;
( - 4 )^2 - 4 * ( 1 )c = 0
,
16 – 4c = 0
,
4c = 16
,
c = 4
,
<em>Solution; The expression is, therefore; x^2 – 4c + 4</em>
