Represent the polynomial x2 – 16 geometrically using algebra tiles. The number of zero pairs that will be added to the board is . The equivalent factored form of x2 – 16 is .

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.
