Nick and Josh were trying to solve the 3x2 + 8x +4= 0 by the equation method of completion of squares. While trying to complete the squares, in one of the steps nick subtracted 4/3 whole square whereas the steps, Josh subtracted 7/6 whole and both of them calculated the roots. Their teacher looked at the roots and told them that Nick's roots are the additive inverses of Josh’s roots. Please explain today is my exam please please

Step-by-step explanation:
Given quadratic equation = √3x² - 8x + 4√3 = 0
We should factorize the equation first.
=√3x²-6x-2x+4√3 = 0
= √3x(x-2√3)-2(x-2√3) = 0
= (√3x-2) (x-2√3) = 0
= (√3x-2) = 0 , (x-2√3) = 0
= x = 2/√3 , x = 2√3.

Step-by-step explanation:
x= -2/3 or x= -2
3x²+8x+4=0
=>x²+(8/3)x+4/3=0
=>[x+(4/3)]²-4/9=0
=>[x+(4/3)]²=4/9
=>x+(4/3)=2/3 or (-2/3)
=>x=(2/3)-(4/3) or (-2/3)-(4/3)
=>x= -2/3 or -6/3
=>x = -2/3 or -2
