expand-4(-(piM)/2+5(2pi-4))

expand

- 4 (- \frac{π M}{2} + 5 (2 π - 4))

2 π M - 40 π + 80

Solution steps

- 4 (- \frac{π M}{2} + 5 (2 π - 4))

Apply the distributive law:

a (b + c) = ab + a c

a = - 4, b = - \frac{π M}{2}, c = 5 (2 π - 4)

= - 4 (- \frac{π M}{2}) + (- 4) \cdot 5 (2 π - 4)

Apply minus-plus rules

- (- a) = a, + (- a) = - a

= 4 \cdot \frac{π M}{2} - 4 \cdot 5 (2 π - 4)

Simplify

4 \cdot \frac{π M}{2} - 4 \cdot 5 (2 π - 4) : 2 π M - 40 π + 80

= 2 π M - 40 π + 80

\frac{2 x - 5}{( x - 1 ) ( x - 4 )}

\frac{d ^{2}}{d x ^{2}} ((y) (4 x - 1))

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

(x - π)^{4}

(2 x + 4 y = - 12) \cdot (- 5)
