Question

$9 x^{2} -3 \frac{x}{2} =0$

Answer 1

$9 x^{2} -3 \frac{x}{2} =0 \\ \\ mmc=2 \\ \\ 18 x^{2} -3*x=0 \\ \\\\ 18 x^{2} -3x=0 \\\\ \\ x(18x-3)=0\\\\ x=0\\\\ 18x-3=0\to 18x=3\to x= \frac{3}{18} \to x= \frac{1}{6}$


$S=(0; \frac{1}{6} )$

Answer 2

18x² - 3x = 0

3x(6x - 1) = 0

3x1= 0 ==> x1 = 0

6x2 - 1 = 0 ==> 6x2 = 1==> x2 = 1
