expand (1-e^t)^2

Solution

expand

(1 - e^{t})^{2}

Solution

1 - 2 e^{t} + e^{2 t}

Solution steps

(1 - e^{t})^{2}

Apply Perfect Square Formula:

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

a = 1, b = e^{t}

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

Simplify

1^{2} - 2 \cdot 1 \cdot e^{t} + (e^{t})^{2} : 1 - 2 e^{t} + e^{2 t}

= 1 - 2 e^{t} + e^{2 t}
