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

Solution

expand

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

Solution

- 5 k^{4} + 20 k^{3}

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

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

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

Simplify

- 5 k^{2} k^{2} - (- 5 k^{2}) \cdot 4 k : - 5 k^{4} + 20 k^{3}

= - 5 k^{4} + 20 k^{3}
