expand x^2(x^2-4)

Solution

expand

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

Solution

x^{4} - 4 x^{2}

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

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

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

Simplify

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

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