Answer

Final Answer: The discriminant of the equation \(5x^{2}+5x+7=0\) is \(\boxed{-115}\).

Steps

Step 1 :Let's find the discriminant of the equation \(5x^{2}+5x+7=0\). The discriminant is given by the formula \(D = b^{2} - 4ac\).

Step 2 :Substitute \(a = 5\), \(b = 5\), and \(c = 7\) into the formula.

Step 3 :Calculate the discriminant \(D = (5)^{2} - 4*5*7\).

Step 4 :The discriminant \(D = -115\).

Step 5 :Since the discriminant is less than 0, the quadratic equation has two complex solutions.

Step 6 :Final Answer: The discriminant of the equation \(5x^{2}+5x+7=0\) is \(\boxed{-115}\).
