Solve for x. Round your answer to the nearest hundredth.
Dmitriy789 [7]

Answer:


Step-by-step explanation:

Here we need to find the x for the given equation so we can use the concept of the quadratic formula to solve .

comparing the given equation with an standard quadratic equation we get

a=1

b=6

c=3

so applying the quadratic formula we get

x=\frac{-6+-\sqrt{6^2-4*1*3} }{2*1}

x=\frac{-6+-\sqrt{24} }{2}

which can be further simplified to get

x=-5.45 or x=-0.55

so correct option is <em>A</em>
