expand 8r^2(r^2-2)

Solution

expand

8 r^{2} (r^{2} - 2)

Solution

8 r^{4} - 16 r^{2}

Solution steps

8 r^{2} (r^{2} - 2)

Apply the distributive law:

a (b - c) = ab - a c

8 r^{2} (r^{2} - 2) = 8 r^{2} r^{2} - 8 r^{2} \cdot 2

= 8 r^{2} r^{2} - 8 r^{2} \cdot 2

Simplify

8 r^{2} r^{2} - 8 r^{2} \cdot 2 : 8 r^{4} - 16 r^{2}

= 8 r^{4} - 16 r^{2}
