expand-4b(-2be^2-4)

expand

- 4 b (- 2 b e^{2} - 4)

8 e^{2} b^{2} + 16 b

Solution steps

- 4 b (- 2 b e^{2} - 4)

= - 4 b (- 2 e^{2} b - 4)

Apply the distributive law:

a (b - c) = ab - a c

a = - 4 b, b = - 2 b e^{2}, c = 4

= - 4 b (- 2 b e^{2}) - (- 4 b) \cdot 4

Apply minus-plus rules

- (- a) = a

= 4 \cdot 2 e^{2} bb + 4 \cdot 4 b

Simplify

4 \cdot 2 e^{2} bb + 4 \cdot 4 b : 8 e^{2} b^{2} + 16 b

= 8 e^{2} b^{2} + 16 b

\frac{3}{( x + 5 ) ^{3}}

\frac{1}{( 2 x + 1 ) ^{3}}

\frac{2}{( 1 - x ) ( 2 - x )}

\frac{1}{8} (420 + ln (41))

(3 e^{x} + 3 c)^{2}
