Answer:
x= -2/3
Step-by-step explanation:
The best way to solve this problem is through completing the square so
![y=-6-4x-3x^2\\y=-3x^2-4x-6\\y=-3(x^2+\frac{4}{3} x)-6\\y=-3(x^2+\frac{4}{3} x+\frac{4}{9} -\frac{4}{9})-6\\y=-3(x^2+\frac{4}{3} x+\frac{4}{9})-6+\frac{4}{3} \\y=-3(x+\frac{2}{3} )^{2} -\frac{14}{3} \\](https://tex.z-dn.net/?f=y%3D-6-4x-3x%5E2%5C%5Cy%3D-3x%5E2-4x-6%5C%5Cy%3D-3%28x%5E2%2B%5Cfrac%7B4%7D%7B3%7D%20x%29-6%5C%5Cy%3D-3%28x%5E2%2B%5Cfrac%7B4%7D%7B3%7D%20x%2B%5Cfrac%7B4%7D%7B9%7D%20-%5Cfrac%7B4%7D%7B9%7D%29-6%5C%5Cy%3D-3%28x%5E2%2B%5Cfrac%7B4%7D%7B3%7D%20x%2B%5Cfrac%7B4%7D%7B9%7D%29-6%2B%5Cfrac%7B4%7D%7B3%7D%20%5C%5Cy%3D-3%28x%2B%5Cfrac%7B2%7D%7B3%7D%20%29%5E%7B2%7D%20-%5Cfrac%7B14%7D%7B3%7D%20%5C%5C)
