Answer

\begin{align*} \text{Discriminant: }& -116 \\\text{Number of Real Solutions: }& 0 \end{align*}

Work Step by Step

In the given equation, \begin{align*} 6x^2-2x+5=0 ,\end{align*} $a= 6 ,$ $b= -2 ,$ and $c= 5 .$ Using the Discriminant Formula which is given by $b^2-4ac,$ the value of the discriminant is \begin{array}{l}\require{cancel} & (-2)^2-4(6)(5) \\&= 4-120 \\&= -116 \end{array} Since the discriminant is less than $0,$ then there is no real solution. Hence, \begin{align*} \text{Discriminant: }& -116 \\\text{Number of Real Solutions: }& 0 \end{align*}
