The given quadratic equation is:
2x^2 - 3x - 5
The standard form of a quadratic equation is:
ax^2 + bx + c
Comparing the given equation with the standard form, we can identify that:
a = 2
b = -3
c = -5
Therefore, the values of a, b, and c in the given quadratic equation are 2, -3, and -5 respectively.
