Answer:

No real solutions.

B is correct

Step-by-step explanation:

Given: \(3x^2+x+10=0\)

We are given a quadratic equation and need to solve for x.

Quadratic formula: \(ax^2+bx+c=0\)

\(x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\)

For our equation, a=3, b=1 and c=10

Substitute the value of a, b and c into formula

\(x=\dfrac{-1\pm\sqrt{1^2-4\cdot 3\cdot 10}}{2\cdot 3}\)

\(x=\dfrac{-1\pm\sqrt{-119}}{6}\)

Here, Roots are imaginary because number inside the square root is negative.

Hence, No real solutions.
