expand x^2(4x-2y)

Solution

expand

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

Solution

4 x^{3} - 2 x^{2} y

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

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

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

Simplify

x^{2} \cdot 4 x - x^{2} \cdot 2 y : 4 x^{3} - 2 x^{2} y

= 4 x^{3} - 2 x^{2} y
