12y%5E2-1=44%281-y%29
12y%5E2-1=44%28-y%2B1%29
12y%5E2-1=-44y%2B44
12y%5E2%2B44y-1=-44y%2B44y%2B44
12y%5E2%2B44y-1=0%2B44
12y%5E2%2B44y-1=44
12y%5E2%2B44y-1-44=44-44
12y%5E2%2B44y-45=0
Using the quadratic formula,
y=%28-44%2B-sqrt%2844%5E2-4%2A12%2A%28-45%29%29%29%2F%282%2A12%29
y=%28-44%2B-sqrt%281936%2B2160%29%29%2F%2824%29
y=%28-44%2B-sqrt%284096%29%29%2F%2824%29
y=%28-44%2B-+64%29%29%2F%2824%29
y=%28-44%2B64%29%2F%2824%29 or y=%28-44-64%29%2F%2824%29
y=20%2F24=5%2F6 or y=-108%2F24=-54%2F12=-27%2F6=-9%2F2

12Y^2-1=44(1-Y)
12Y^2-1=44-44Y
12Y^2+44Y-1-44=0
12Y^2+44Y-45=0
(2Y+9)(6Y-5)=0
2Y+9=0
2Y=-9
Y=-9/2
Y=-4.5 ANSWER.
6Y-5=0
6Y=5
Y=5/6 OR .8333 ANSWER.
