put x=2 And x=1/2 in equation
4p +10 +r =0
p/4 +5/2 +r=0
4p +10 +r=p/4 +5/2 +r
4p +10 =p/4 +5/2
16 p + 40 =p +10 (× 4)
16p-p=10-40
15p=-30
p = -2
Now put p=-2
4p +10 +r =0
-8+10 +r =0
2+r=0
r=-2
p=r=-2 verified
4p +10 +r =0
p/4 +5/2 +r=0
4p +10 +r=p/4 +5/2 +r
4p +10 =p/4 +5/2
16 p + 40 =p +10 (× 4)
16p-p=10-40
15p=-30
p = -2
Now put p=-2
4p +10 +r =0
-8+10 +r =0
2+r=0
r=-2
p=r=-2 verified
