Answer 2

Answer:

The answer is - root 3/2 and - root 3/2

Here is your answer given below step by step hope it helps and pls mark it as brainliest too

Step-by-step explanation:

We have 4x^2  + 4 root  3x  + 3 = 0

On dividing both sides by 4 we have

x^2  + root  3x  +  4 /3  = 0

⇒ x^2 +  root 3x  +(  root 3 /2​ )^2  −(root 3 /2​ )^2  +  3/4  = 0

⇒ (x+ root 3 /2  )^2  −  3/4 ​   + 3/4 =0  ⇒ (x +   root 3/2 )^2  =0....(i)

Roots exist

∴ (i) ⇒ x=−  root 3/2 ,−  root 3/2
