number 2

inkyvoyd · Answer

x cannot be 5, because that's undefined. difference of squares: (a+b)(a-b)=a^2-b^2

campbell_st · Answer

the numerator factorises to(x -5)(x+5)

eliminate the common factor to get the answer

campbell_st · Answer

restriction is what value of x make the denominator zero   x - 5 = 0
