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}}}
