expand (3y^2-20x^2y)dy

expand

(3 y^{2} - 20 x^{2} y) d y

3 y^{2} d y - 20 y x^{2} d y

Solution steps

(3 y^{2} - 20 x^{2} y) d y

= (3 y^{2} - 20 y x^{2}) d y

Apply the distributive law:

a (b - c) = ab - a c

a = d y, b = 3 y^{2}, c = 20 x^{2} y

= d y \cdot 3 y^{2} - d y \cdot 20 x^{2} y

= 3 y^{2} d y - 20 y x^{2} d y

\frac{4}{( x - 1 ) ^{2} ( x - 3 ) ( x + 1 )}

\frac{( x - 1 ) z}{2 z - 4 t + 1}

- \frac{1}{2 ( 5 + 4 s - s ^{2} )}

\frac{( x ^{2} + 7 ) ^{2}}{x ^{5}}

(- 4 x B)^{4}
