What values of a, b, and c would you use in the quadratic formula for the following equation

5x^2+9x=4

The given equation is 5x^2 + 9x = 4. This can be rewritten in the standard form of a quadratic equation:

ax^2 + bx + c = 0

Comparing the given equation with the standard form, we can see that a = 5, b = 9, and c = -4.

Therefore, to use the quadratic formula for this equation, you would plug in a = 5, b = 9, and c = -4.
