Question

Find all possible non zero integers for a for which a×a=a

Answer 1

Answer:

we have,

=> a×a=a

=> a^2=a

=> a^2 –a=0

=> a(a–1)=0

=> a=0 (neglected) or a=1

thus,we get only one integer ie, 1 .

such that a×a=a.

here, we will neglect a=0,

because in the question it is asked for non zero integers.
