expand (x-e^y)^2

Solution

expand

(x - e^{y})^{2}

Solution

x^{2} - 2 e^{y} x + e^{2 y}

Solution steps

(x - e^{y})^{2}

Apply Perfect Square Formula:

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

a = x, b = e^{y}

= x^{2} - 2 x e^{y} + (e^{y})^{2}

Apply exponent rule:

(a^{b})^{c} = a^{b c}

= x^{2} - 2 e^{y} x + e^{2 y}
