Question

Eight times the square of a positive integer divided by two equals 144 minus 36 times the positive integer. Find the unknown positive integer.

Answer 1

I assume this is what you meant...
8$y^{2}$ /2 = 144- 36y
**multiply 2 to both sides
**get all terms to one side
0= 8$y^{2}$ + 72y -288
time to factor 
8(y+12)(y-3)
y+ 12 =0 --> y= -12
y - 3 =0 --> y= 3
