Any square is greater or equal 0. Therefore the formula possess the least value when (x – 2)² = 0. x – 2 = 0 x = 2 The correct answer is choice (D). ---------- Can you please explain how the +10 was broken down into the +4) + 6? I was able to get to 2 × (x² - 4x+10) but not any further.
Also, what's the rationale behind x = 2 and knowing that the 0 quantity will be the least quantity for y. Is that just a number line concept? I can't help but work out every answer choice just to be sure.
