recall in a perfect square trinomial, the middle term is the tale-tell guy, we know the middle term is the product of 2 and the two other guys without the exponent, so in this case 6x = 2*√x² * √c.

Y = -3(2) +22
Y = -6 +22
Y = 16
No, 6,500 is one hundred times as much as 65, because of the two zeros on the end. 100 and 6,500.
