Answer :
Final answer:
The discriminant of the quadratic equation 5x^2 + 9x + 7 = 0 is -59.
Explanation:
The discriminant of a quadratic equation is a value determined using the coefficients of the equation. For the quadratic equation 5x2 + 9x + 7 = 0, the discriminant can be calculated using the formula:
Discriminant = b2 - 4ac
Where a, b, and c are the coefficients of the quadratic equation (in this case, a = 5, b = 9, c = 7).
Substituting the values into the formula, we get:
Discriminant = (9)2 - 4(5)(7)
Discriminant = 81 - 140
Discriminant = -59
Therefore, the discriminant of the quadratic equation 5x2 + 9x + 7 = 0 is -59.
