Answer:

6 and -1

Explanation:

If you take the equation and set it to be 0, you can find the input values that make it 0.


x^2-5x-6=0

Since this is a quadratic, equation you can use the quadratic formula with the values:

  • a = 1
  • b = -5
  • c = -6

The quadratic formula is:


x=(-b \pm √(b^2-4ac))/(2a)

If you plug the values for a, b, and c, you get:

x = 6 and x = -1
