expand (u-2)^2

Solution

expand

(u - 2)^{2}

Solution

u^{2} - 4 u + 4

Solution steps

(u - 2)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

u^{2} - 2 u \cdot 2 + 2^{2} : u^{2} - 4 u + 4

= u^{2} - 4 u + 4
