7×8=56

7+8=15

Answer 2

Answer:

the two numbers will be 7 and 8

Step-by-step explanation:

let x and y be two numbers

product= xy=56

sum=x+y=15

now, x=56/y

56/y + y=15

(56+y^2)/y=15

56+y^2=15y

y^2-15y+56=0

y^2-8y-7y+56=0

y(y-8)-7(y-8)=0

y=7,8

when y=7

then 7x=56

x=56/7

x=8

when y=8

then 8x=56

x=7

7*8=56

7+8=15
