Explanation:

${ \purple{ \tt{(X₁ + X₂)²}}}$

This above problem is in the form of

${ \blue{ \tt{ {(a + b)}^(2)}}}$

where the expanded form of

${ \blue{ \tt {(a + b)}^(2)}} = { \green{ \bold{ {a}^(2) + {b}^(2) + 2ab}}}$

then the (X₁ + X₂)² answer will be

${ \purple{ \tt{(X₁ + X₂)²}}} = { \purple{ \tt{ {X₁}^(2) + {X₂}^(2) + 2X₁X₂}}}$
