factor z^2-4z+4

Solution

factor

z^{2} - 4 z + 4

Solution

(z - 2)^{2}

Solution steps

z^{2} - 4 z + 4

Rewrite in the form of

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

4 = 2^{2}

- 4 z = - 2 z \cdot 2

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

Apply Perfect Square Formula:

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

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

= (z - 2)^{2}
