a)4/3x²=0 ==> x² = 0/4 ==> x² = 0 ==> x = 0
=====================================================
b)4/3x²-3=0
==> 4x² = 3 ==> 4x² = 9 ==> x = +/-√9/4 ==> +/- 3/2
3
======================================================
c)7x²-10=0
==> 7x² = 10 ==> x² = 10
7
x = +/-√10 ==> x = +/-√10.√7 ==> x=+/- √70
