expand (2x-5)(4x^2)

Solution

expand

(2 x - 5) (4 x^{2})

Solution

8 x^{3} - 20 x^{2}

Solution steps

(2 x - 5) (4 x^{2})

= (4 x^{2}) (2 x - 5)

Apply the distributive law:

a (b - c) = ab - a c

(4 x^{2}) (2 x - 5) = 4 x^{2} \cdot 2 x - 4 x^{2} \cdot 5

= 4 x^{2} \cdot 2 x - 4 x^{2} \cdot 5

Simplify

4 x^{2} \cdot 2 x - 4 x^{2} \cdot 5 : 8 x^{3} - 20 x^{2}

= 8 x^{3} - 20 x^{2}
