Question

if the sum of two number is 48 and their product is 320,then what is the large number? ​

Answer 1

Step-by-step explanation:

let the two numbers be x and y

According to the question

x+y=48 Equation 01

And

xy=320 Equation 02

From 01 and 02

x+(320/x)=48

x²+320=48x

x²-48x+320=0

x²-40x-8x+320=0

x(x-40)-8(x-40)=0

x=8 And x = 40

For x = 8 y = 40

And

For x=40 y = 8

Therefore largest number is 40
