Find two numbers whose product is 100 and whose sum is a maximum?
brilliants [131]
Let them be X and Y..
now...
yx=100 ....
y=100/y ...
now...
x+y= s....where s is their sum...
but y=100/x
now....x+100/x=s..
by differentiating both sides with respect to x..
1-100/x^2=ds/dx
but ds/dx=0..
100=x^2 ..
x=10..
so y=10

Answer:

2

Step-by-step explanation:

x2+3x=6

Step 1: Subtract 6 from both sides.

x2+3x−6=6−6

x2+3x−6=0

For this equation: a=1, b=3, c=-6

1x2+3x+−6=0

Step 2: Use quadratic formula with a=1, b=3, c=-6.

x=

−b±√b2−4ac

2a

x=

−(3)±√(3)2−4(1)(−6)

x=
