Question

for what value of m the product of The roots of equation x²+21x+(m+8)is 13?​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

5

Step-by-step explanation:

eq is x^2+21x+(m+8)=0

then

comparing a=1

b=21

c=(m+8)

we know

product of the roots=c/a

c/a=m+8/1=13

m+8=13

m=13-8

m=5
