expand (2a-b)^2

Solution

expand

(2 a - b)^{2}

Solution

4 a^{2} - 4 ab + b^{2}

Solution steps

(2 a - b)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

(2 a)^{2} - 2 \cdot 2 ab + b^{2} : 4 a^{2} - 4 ab + b^{2}

= 4 a^{2} - 4 ab + b^{2}
