HERE IS YOUR ANSWER
____________________
= f(x) = px^2+5x+r
factors are x-2 , x-1/2
Substitute x = 2 in place of equation
____________________________
= p*2^2+5*2+r=0
= 4p + 10 + r = 0 ------------ (i)
Substitute x = 1/2 in place of equation.
__________
= p/4 + 5/2 + r = 0
= p + 10 + 4r = 0 ------------- (ii)
On solving (i) , (ii)
_____________
= 4p+r=-10 and p+4r+10=0
= 4p+r=p+4r
= 3p=3r
p = r.
___________________________
correct option is (d). r
