Answer 2

Answer:

13/3 or -1/3

Step-by-step explanation:

$3x^2 - 12x - 5=0\\=> a=3; b=-12; c=-5\\x=\frac{-b+\sqrt{b^2-4ac} }{2a}$

or  $\frac{-b-\sqrt{b^2-4ac} }{2a}$

$x = \frac{12+\sqrt{144+60}}{6}$

or   $\frac{12-\sqrt{144+60}}{6}$

$x = \frac{12+14}{6}$

or   $\frac{12-14}{6}$

Therefore, x = 13/3 or -1/3
