Identify Coefficients: The discriminant of a quadratic equation $ax^2 + bx + c = 0$ is given by the formula $D = b^2 - 4ac$ . We need to identify the coefficients $a$ , $b$ , and $c$ from the given equation and then calculate the discriminant.
Given Quadratic Equation: The given quadratic equation is $3x^2 - 3x - 7 = 0$ . Here, the coefficient $a$ is $3$ , the coefficient $b$ is $-3$ , and the coefficient $c$ is $-7$ .
Substitute Values: Now we will substitute the values of $a$ , $b$ , and $c$ into the discriminant formula $D = b^2 - 4ac$ . So, $D = (-3)^2 - 4(3)(-7)$ .
Calculate Discriminant: Calculating the discriminant, $D = 9 - 4(3)(-7) = 9 + 84 = 93$ .
