Answer:

#x in (5/3,2)#

Explanation:

#(3x-5)(x-2)# is the equation of a parabola
with x-intercepts at #5/3# and #2#

If expanded into standard form the leading term is #3x^2#

#rArr# the leading term coefficient is positive

#rArr# the parabola opens upward

#rArr# the points between the x-intercepts are below the X-axis

#rArr# the value of the parabola is #< 0# when #x in (5/3, 2)#
