Answer 2

$y=\frac{23}{3}$ , $y=1$

விளக்கம்:

$3 y^{2}-20 y-23=0$

$a=3, b=-20, c=-23$

$y=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

$=\frac{-(-20) \pm \sqrt{(-20)^{2}-4(3)(-23)}}{2(3)}$

$=\frac{20 \pm \sqrt{400+276}}{6}$

$y=\frac{20 \pm \sqrt{676}}{6}$

$y=\frac{20 \pm 26}{6}$

$y=\frac{46}{6}$

$y=\frac{23}{3}$

$y=\frac{20-26}{6}$

$y=\frac{-6}{6}$

$y=1$

$y=\frac{23}{3}$ , $y=1$
