4 x^{2} - 16 x + 16

Solution steps

(- 2 x + 4)^{2}

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

(- 2 x + 4)^{2} = (- 2 x)^{2} + 2 (- 2 x) \cdot 4 + 4^{2}

= (- 2 x)^{2} + 2 (- 2 x) \cdot 4 + 4^{2}

Simplify

(- 2 x)^{2} + 2 (- 2 x) \cdot 4 + 4^{2} : 4 x^{2} - 16 x + 16

= 4 x^{2} - 16 x + 16
