Could you please explain how to solve these two sums, step by step please.
This is as far as I got on both sums:
Any help would be greatly appreciated,
Not okay, you divided by x; you can do that, but this is only for ; and x = 0 is a solution!
now you know x = 0 is a solution and x²-8 = 0 leads to the other solutions; you still have to solve x²-8= 0, tho.
