A student's work in solving an equation is shown below:
4x2 + 2x = 0
2x (2x+1= G
2x+/= 0
2x=-1
=-{-1/
Determine if there's an error in the student's work. If there is, explain what the error is,
and correct it.
Yes there is an error in the student's work. The error is that he is considering only single value of x. To correct the error he/she must calculate all the possible values of x. The process is shown in the paper.
