(e + f)^{2} - g^{2}

e^{2} + 2 e f + f^{2} - g^{2}

求解步骤

(e + f)^{2} - g^{2}

(e + f)^{2} : e^{2} + 2 e f + f^{2}

= e^{2} + 2 e f + f^{2} - g^{2}

e x p an d \frac{( - 4 - b ) i + 2 - 2 b}{5}

e x p an d \frac{( y )}{( 2 a - 1 ) ( 4 a - 5 )}

e x p an d (2 x^{2} y^{3} + 3 y^{5} - 20 y^{3}) d x

e x p an d \frac{10 x}{( x ^{2} + 5 ) ^{2}}

e x p an d (x^{2} - 5) y^{'} (x) - 2 x y
