Jiayang's answer to Mutya's International Baccalaureatte Maths SL question.
Why should we equote wtv is in bracket to 0?

(x-1)² ≥ 0
In order to get a minimum value out of (x-1)², we see that we have to equate x-1=0.

Hi Jiayang, Happy New Year to you and the students. Just wonder what device and app you are using to write the solutions. It's clear and pleasing to the eye. Care to share? Sorry I couldn't get to you by other means. Thanks & cheers.
