expand 2sqrt(x)(x^2-9)

expand

2 x (x^{2} - 9)

2 x^{2} x - 18 x

Solution steps

2 x (x^{2} - 9)

Apply the distributive law:

a (b - c) = ab - a c

2 x (x^{2} - 9) = 2 x x^{2} - 2 x \cdot 9

= 2 x x^{2} - 2 x \cdot 9

Simplify

2 x x^{2} - 2 x \cdot 9 : 2 x^{2} x - 18 x

= 2 x^{2} x - 18 x

(2 + 3) 2

2 x^{2} + 3 y^{3} - (x^{3} + 2 x y^{2}) y^{'} (x)

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

x - 2^{2}

(x - 3 y)^{2}
