First, the environmental reasons are actually easy to understand. Some children can't adapt to the present environment, so at this time, the children themselves will feel very nervous. So we must analyze it according to our own situation. If you find that your child's math scores suddenly become particularly poor, it may be because the child can't adapt to the new environment at this time. It may be because the child is now in junior high school, so at this time, the child will feel unfamiliar with his environment, and at this time, the students are faced with new teachers and new classmates, so the child will feel very nervous at this time.
Second, the psychological reason may be that the child has some problems. If the child is introverted and may not be willing to communicate with his parents or teachers when he encounters difficulties, then the child will encounter many problems himself at this time. Therefore, parents must pay attention to their children. It may be because there are some problems in the child's own mentality. At this time, parents must promptly guide them.
However, this problem is also common. Parents don't need to worry too much, but if you find this problem, it is time to communicate with your child. If this problem is not solved, then the child may become particularly insecure at this time.
Since the denominators of the equation are (x-3) and (3-x) require that x¡Ù3 is true, the solution x=0 is an effective solution.
