expand 4x(x^2-9)

Solution

expand

4 x (x^{2} - 9)

Solution

4 x^{3} - 36 x

Solution steps

4 x (x^{2} - 9)

Apply the distributive law:

a (b - c) = ab - a c

4 x (x^{2} - 9) = 4 x x^{2} - 4 x \cdot 9

= 4 x x^{2} - 4 x \cdot 9

Simplify

4 x x^{2} - 4 x \cdot 9 : 4 x^{3} - 36 x

= 4 x^{3} - 36 x
