expand (h-2)^2

Solution

expand

(h - 2)^{2}

Solution

h^{2} - 4 h + 4

Solution steps

(h - 2)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

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

= h^{2} - 4 h + 4
