The velocity V of a blood corpuscle in a vessel depends on the distance r from the center of the vessel and is given by the equation Vr= Vm(1-r2/R2), where Vm is the maximum velocity and R the radius of the vessel. Multiply this expression.

$v_r = v_m\left(1 - \frac{r^2}{R^2}\right)
$

ok ... distribute $v_m$ on the right side.
