expand (b-1)^2

Solution

expand

(b - 1)^{2}

Solution

b^{2} - 2 b + 1

Solution steps

(b - 1)^{2}

Apply Perfect Square Formula:

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

(b - 1)^{2} = b^{2} - 2 b \cdot 1 + 1^{2}

= b^{2} - 2 b \cdot 1 + 1^{2}

Simplify

b^{2} - 2 b \cdot 1 + 1^{2} : b^{2} - 2 b + 1

= b^{2} - 2 b + 1
