Matrix labeling items contain a grid in which elements are in rows, and the labels are column headers. Depending on the item, labels may be used more than once. Users select a label for each element by filling in answer bubbles at the intersections of rows and columns.

- Select the
*x*value that makes each equation true. -
*x*= -3*x*= -2*x*= -4*x*= -1*x*^{2}–*x*– 6 = 03 *x*^{2}– 12*x*– 15 = 06 *x*^{2}– 6*x*– 72 = 06 *x*^{2}+ 18*x*– 24 = 0
