You can put this solution on YOUR website! Find two real numbers: x and y:
:
that have a sum of 8
x + y = 8
y = (8-x); use for substitution
:
and a product of 2.
x*y = 2
:
Replace y with (8-x) in the above equation:
x(8-x) = 2
:
8x - x^2 = 2
:
-x^2 + 8s - 2 = 0
:
Use the quadratic formula to find x
In this equation; a=-1; b=8; c=-2
:
:
Two solutions:
:
x = +.258; then y =7.742
and
:
x = +7.742; then y = .258
