Answer:
[tex]\huge\boxed{\sf Option \ A}[/tex]
Step-by-step explanation:
Given expression:
= x² - 4x + 5
We can not factor out this expression, because of we apply mid-term break to it, the factors -4x will break into are -5x + x the coefficients of which when multiplied give -5 and not +5 (side term). This is a known rule in the mid-term break formula.
- So, the given expression is a prime expression.
