expand ((y+1)e^t-x)^2

expand

((y + 1) e^{t} - x)^{2}

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

Solution steps

((y + 1) e^{t} - x)^{2}

Expand

(y + 1) e^{t} - x : e^{t} y + e^{t} - x

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

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

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

Expand

(e^{t} y + e^{t} - x) (e^{t} y + e^{t} - x) : e^{2 t} y^{2} + 2 e^{2 t} y - 2 e^{t} y x + e^{2 t} - 2 e^{t} x + x^{2}

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