25y^2+60y+36-24=0
25y^2+60y+8 =0
disctirminant =60^2-4.25.8
disctirminant =3600-800
disctirminant =2800
x1= -60+square root of 2800/2.25
x1= -60+52.91/50= -7.09/50= -0.14
x2= -60- square root of 2800/2.25
x2= -60-52.91/50
x2= -2.25
The square root of 20 does not give an integer solution or fraction so it is irrational
