factor 4-4x+x^2

factor

4 - 4 x + x^{2}

(x - 2)^{2}

Solution steps

4 - 4 x + x^{2}

Write in the standard form

= x^{2} - 4 x + 4

Rewrite in the form of

a^{2} + 2 ab + b^{2} :

4 = 2^{2}

- 4 x = - 2 x \cdot 2

= x^{2} - 2 x \cdot 2 + 2^{2}

Apply Perfect Square Formula:

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

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

= (x - 2)^{2}

(27)^{2}

8 y^{3} + 10 y^{2} + 3 y

(\frac{3}{2})^{- 4}

\frac{62}{27} + \frac{65}{44}

(\frac{4 s ^{5} t ^{- 7}}{- 2 s ^{- 2} t ^{4}})^{3}
