expand (z-8)^2

Solution

expand

(z - 8)^{2}

Solution

z^{2} - 16 z + 64

Solution steps

(z - 8)^{2}

Apply Perfect Square Formula:

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

(z - 8)^{2} = z^{2} - 2 z \cdot 8 + 8^{2}

= z^{2} - 2 z \cdot 8 + 8^{2}

Simplify

z^{2} - 2 z \cdot 8 + 8^{2} : z^{2} - 16 z + 64

= z^{2} - 16 z + 64
