Question

Find the value of p in quadratic polynomial x2-px+12 if alpha square + beta square is 24

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer

alpha+beta=-b/a

=p/1

=p

alpha×beta=c/a

=12/1

=12

Now

(alpha+beta)^2=alpha square+beta square+2alpha×beta

Step-by-step explanation

P^2=24+2×12

=24+24

=48

Hence p=√48

P=+4√3 and -4√3
