Question

What are the solutions of 3x^2+6x+6=0

Answer 1

x= -1+i; -1-i

Explanation:

Answer 2

x = -1 + i, -1 - i,

Explanation:

3x^2 + 6x + 6 = 0

Divide through by 3:

3(x^2 + 2x+ 2) = 0

Using the quadratic formula

x = [-2 +/- √2^2 - 4*1*2) ] / 2

x = ( -2 +/- √-4 ) / 2

x = (-2 +/- 2i)/ 2

x = -1 + i , -1 - i,
