expand (2-2t)^2

Solution

expand

(2 - 2 t)^{2}

Solution

4 - 8 t + 4 t^{2}

Solution steps

(2 - 2 t)^{2}

Apply Perfect Square Formula:

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

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

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

Simplify

2^{2} - 2 \cdot 2 \cdot 2 t + (2 t)^{2} : 4 - 8 t + 4 t^{2}

= 4 - 8 t + 4 t^{2}
