X²=3x

Therefore,

X²-3x=0

By moving all factors to the left.

Now for each factor being equal to zero.

1. X²=0

Square becomes square root when crossing the equality sign to make X the subject of formula.

X=√0

X=0

2. -3x=0

X=3

By making X the subject of formula.

When the negative sign crosses the equality sign, it becomes positive.

So x=0,3

This reminds me so much about solving problems back in secondary school. I didn't like solving problems at all. I was just an average student when it came to that. I never enjoyed it and I only read to pass. I wouldn't even practice them until it was time for examination.
