expand (z+4)^2

Solution

expand

(z + 4)^{2}

Solution

z^{2} + 8 z + 16

Solution steps

(z + 4)^{2}

Apply Perfect Square Formula:

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

(z + 4)^{2} = z^{2} + 2 z \cdot 4 + 4^{2}

= z^{2} + 2 z \cdot 4 + 4^{2}

Simplify

z^{2} + 2 z \cdot 4 + 4^{2} : z^{2} + 8 z + 16

= z^{2} + 8 z + 16
