Find the value of X when 3x^2 + 6x + 3 = 0

Firstly we can see that this equation can be simplified. They are all divisible by 3 so this means we can simplify it to x^2 + 2x + 1 =0 Now we need to find what times together equals 1 but when added together equals 2. The only value for this is 1.So (x+1)^2 = 0This means x = -1
