expand (e^t+1)^2

Solution

expand

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

Solution

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

Solution steps

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

Apply Perfect Square Formula:

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

a = e^{t}, b = 1

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

Simplify

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

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