eqn=px2-5x+p=0----eqn1
if eqn has real and equal roots
b2-4ac=0---eqn 2
here in the eqn
a=p; b=-5; c=p
putting the values in the eqn2
(-5)^2-4(p)(p)=0
25-4p^2=0
25=4p^2
p^2=25/4
p=√25/4
p=5/2
if eqn has real and equal roots
b2-4ac=0---eqn 2
here in the eqn
a=p; b=-5; c=p
putting the values in the eqn2
(-5)^2-4(p)(p)=0
25-4p^2=0
25=4p^2
p^2=25/4
p=√25/4
p=5/2
