For the CRD, any difference among experimental units receiving the same treatment is considered as experimental error. Hence, CRD is appropriate only for experiments with homogeneous experimental units, such as laboratory experiments, where environmental effects are relatively easy to control.
I. 6x² - 13 x + 6 = 0
II. 15 y² + 11 y - 12 = 0
