expand (d+e)^2-2(d+e)-8

expand

(d + e)^{2} - 2 (d + e) - 8

d^{2} + 2 d e + e^{2} - 2 d - 2 e - 8

Solution steps

(d + e)^{2} - 2 (d + e) - 8

Expand

- 2 (d + e) : - 2 d - 2 e

= (d + e)^{2} - 2 d - 2 e - 8

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

= d^{2} + 2 d e + e^{2} - 2 d - 2 e - 8

\frac{d}{d x} ((z (x, y)) (x + y) e^{y})

\frac{( - 20 - 7 x ) ^{2}}{4}

\frac{8 s}{( s - 1 ) ( s + 2 ) ( s + 3 )}

\frac{10 ( 3 - 7 )}{7}
