Ответ:
The correct option is A) x = -8/3, –2.
Step-by-step explanation:
Consider the provided equation![3x^2 + 14x + 16 = 0](/tpl/images/0482/0507/afccb.png)
The above equation is in the form of![ax^2 +bx + c = 0](/tpl/images/0482/0507/559b3.png)
The quadratic formula to find the root of the equation is:
By comparing the above equation with the general equation we can conclude that:
a = 3, b = 14, and c = 16
Substitute the respective values in the above formula:
Hence the solutions of the provided equation is
.
Thus, the correct option is A) x = -8/3, –2.
