Final answer:
To compute the discriminant of the quadratic equation 7x^2 - 4x + 7 = 0, you can use the formula b^2 - 4ac. Plugging in the values a = 7, b = -4, and c = 7, the discriminant is -180.
Step-by-step explanation:
To compute the discriminant of a quadratic equation, you can use the formula b^2 - 4ac, where the quadratic equation is in the form ax^2 + bx + c = 0. In this case, the quadratic equation is 7x^2 - 4x + 7 = 0. So, a = 7, b = -4, and c = 7.
Now, you can calculate the discriminant:
Discriminant = b^2 - 4ac = (-4)^2 - 4(7)(7) = 16 - 196 = -180.
