(C) For a quadratic equation in the form $ax^{2} + bx + c = 0$,the discriminant $D$ is given by the formula $D = b^{2} - 4ac$.Given the equation $5x^{2} + x + 2 = 0$,we identify the coefficients as $a = 5$,$b = 1$,and $c = 2$.Substituting these values into the formula:$D = (1)^{2} - 4(5)(2)$$D = 1 - 40$$D = -39$Therefore,the value of the discriminant is $-39$.
