Answer:

(-1,0)

Step-by-step explanation:

the equation y = x2 - 10x - 11 = (x-11) (x+1)

Zeroes are at 11 and -1.

(11,0) and (-1,0)

Separation of a quadratic can be solved by finding 2 values that add to the middle number and multiply into the last number. you can also use the intersection tool on a graphing calculator.
