Solution

expand

(u + 4)^{2}

Solution

u^{2} + 8 u + 16

Solution steps

(u + 4)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

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

= u^{2} + 8 u + 16
