Machine Vibration Analysis

A maintenance technician is using the Quadratic Formula to determine the vibration frequency of a machine part modeled by the equation $3p^2 + 2p + 9 = 0.Duringthecalculation,thetechnicianfindsthattheexpressionunderthesquareroot(thediscriminant)evaluatesto. During the calculation, the technician finds that the expression under the square root (the discriminant) evaluates to -104.Basedontherulesofrealnumbers,whatisthefinalconclusionregardingtherealnumbersolutionsforthefrequency. Based on the rules of real numbers, what is the final conclusion regarding the real-number solutions for the frequency p$, and what is the specific reason for this conclusion?
