Question

Plz guys help me to solve this it's urgent​

Answer 1

Step-by-step explanation:

(x-2)=0

so,x=2

put it in given equ.

so we have

px^2+5x+r=0

4p+10+r=0. r=-4p-10

put x=1/2

then we have

p/4+5/2+r=0

p/4+5/2-4p-10=0

p=-2

put it in r=-4p-10

so, r=8-10

=-2

so p=q=-2.

I hope it will help you .
