Question

The sum of to numbers is 45 and their product is 500 what are the two numbers

Answer 1

Answer:

Let numbers be x and y

so

x+y=45     .....1

xy=500     .....2

Step-by-step explanation:

From 2

x=500/y

put in 1

500/y +y=45

y^2-45y+500=0

so solving y=20 and 25

so if y=20 by 1... x =25

or if y=25 by 1... x = 20

Answer 2

Answer:

let the 2 no. are x and y

then

x+y =45....(1)

xy=500....(2)

(x-y)2=(x+y)2-4xy

(45)2-4×500

2025-2000=25

x-y=5....(3)

from equations (1) and(2)

x=25,y=20
