expand

2 π (64 - 322)

128 π - 642 π

Solution steps

2 π (64 - 322)

Apply the distributive law:

a (b - c) = ab - a c

a = 2 π, b = 64, c = 322

= 2 π 64 - 2 π 322

= 2 \cdot 64 π - 2 \cdot 322 π

Simplify

2 \cdot 64 π - 2 \cdot 322 π : 128 π - 642 π

= 128 π - 642 π

\frac{6}{( s + 1 ) ( s + 4 ) s ^{4}}

(6 x - 6 x^{2}) d x

x (4 x^{2} + 5 x - 3 = 0)

6 (X - 5 = 12)
