expand 7e^y(y^2-x^2)

expand

7 e^{y} (y^{2} - x^{2})

7 e^{y} y^{2} - 7 e^{y} x^{2}

Solution steps

7 e^{y} (y^{2} - x^{2})

Apply the distributive law:

a (b - c) = ab - a c

a = 7 e^{y}, b = y^{2}, c = x^{2}

= 7 e^{y} y^{2} - 7 e^{y} x^{2}

- x e^{x} + x (3 + x)

\frac{d ^{2}}{d h ^{2}} ((v) ((3 h^{2} + 4)^{\frac{3}{2}} - 8))

5 (1 - e^{\frac{10}{t}})

\frac{( k ^{3} + 8 k ^{2} + 10 k + 21 )}{( k + 7 )}

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