expand sqrt(2(v*r)+2(r-v))

expand

2 (v \cdot r) + 2 (r - v)

2 v r + 2 r - 2 v

Solution steps

2 (v r) + 2 (r - v)

Remove parentheses:

(a) = a

= 2 v r + 2 (r - v)

Expand

2 v r + 2 (r - v) : 2 v r + 2 r - 2 v

= 2 v r + 2 r - 2 v

3 (4 x + e^{x} + 6)

\frac{1}{( x - y ) ( x + y )}

(x^{'} - 8) (x^{'} + 8)

(- 2, - 3) y (- 2, 3)

(x + 2 y - 1) d x + (x + 2 y - 5) d y
