Step-by-step explanation:

We have to expand,

[tex]\longrightarrow [/tex] (2x — 4)²

(a ― b)² = a² + b² ― 2ab

[tex]\longrightarrow [/tex] (2x)² + (4)² ― 2(2x × 4)

[tex]\longrightarrow [/tex] 4x² + 16 ― 2(8x)

[tex]\longrightarrow [/tex] 4x² + 16 ― 16x

[tex]\longrightarrow [/tex] 4x² ― 16x + 16

Hence, solved!
