expand-2(xln(x)-x)

expand

- 2 (x ln (x) - x)

- 2 x ln (x) + 2 x

Solution steps

- 2 (x ln (x) - x)

Apply the distributive law:

a (b - c) = ab - a c

a = - 2, b = x ln (x), c = x

= - 2 x ln (x) - (- 2) x

Apply minus-plus rules

- (- a) = a

= - 2 x ln (x) + 2 x

2 ((x^{2} + 2) (x + 2))

(10 - 5 e^{- x})^{2}

2 e^{- x^{2} - 4 y^{2}} x - 2 e^{- x^{2} - 4 y^{2}} x (x^{2} + y^{2})

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

\frac{7 x ( x + 1 )}{( x + 3 ) ( x - 3 )}
