Find the zeros of the function y=x^2-1

1, -1

Step-by-step explanation: This is a difference of squares when factored,

(x+1)(x-1)

Let's check using FOIL(First, outside, inside, last)

x * x =x^2

1 *x =x

x * (-1) =-x

1* -1 =-1

so x^2 +x -x -1

=x^2 -1

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
