Question

divide the number 20 into two parts such that their product is maximum​

Answer 1

Hi baby

let x and 20-x be the parts

product =x(20-x)=x²-20x

dp/dx=2x-20

put=dp/dx=0

2x-20=0

2x=20

x=10

d²p/dx²=2

now, d²p/dx² is positive when x=10

so 10,10 is two parts of 20 and their product is maximum

Brainiest answer please.
