A student is asked to solve the quadratic equation 3x² - 4x - 2 = 0 using the Quadratic Formula: (-b +/- sqrt b² - 4ac / 2a)

He uses a= 3 b= -4 c= -2 then plugs in the constants : -4 +/- sqrt (-4)²- 4(3)(-2)/2(3) 

Then simplify

-4 +/- sqrt 16 - 24/6 to -4 +/- sqrt -8/6

His answer is incorrect find the mistake and fix it.

He put -4 instead of switching the sign or -b so he should have put positive four.
