expand ,(2t^2-1)2dt

Solution

expand

(2 t^{2} - 1) 2 d t

Solution

4 t^{2} d t - 2 d t

Solution steps

(2 t^{2} - 1) \cdot 2 d t

= 2 (2 t^{2} - 1) d t

Apply the distributive law:

a (b - c) = ab - a c

a = 2 d t, b = 2 t^{2}, c = 1

= 2 d t \cdot 2 t^{2} - 2 d t \cdot 1

= 2 \cdot 2 t^{2} d t - 2 \cdot 1 \cdot d t

Simplify

2 \cdot 2 t^{2} d t - 2 \cdot 1 \cdot d t : 4 t^{2} d t - 2 d t

= 4 t^{2} d t - 2 d t
