expand (x^2-1)(2x^3)

Solution

expand

(x^{2} - 1) (2 x^{3})

Solution

2 x^{5} - 2 x^{3}

Solution steps

(x^{2} - 1) (2 x^{3})

= (2 x^{3}) (x^{2} - 1)

Apply the distributive law:

a (b - c) = ab - a c

(2 x^{3}) (x^{2} - 1) = 2 x^{3} x^{2} - 2 x^{3} \cdot 1

= 2 x^{3} x^{2} - 2 x^{3} \cdot 1

Simplify

2 x^{3} x^{2} - 2 x^{3} \cdot 1 : 2 x^{5} - 2 x^{3}

= 2 x^{5} - 2 x^{3}
