expand (d-2)^2

Solution

expand

(d - 2)^{2}

Solution

d^{2} - 4 d + 4

Solution steps

(d - 2)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

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

= d^{2} - 4 d + 4
