Question

under the QUADRATIC EQUATION(Roots)
find two positive real numbers whose product is 16 and whose difference is 1.

Answer 1

xy = 16
x-y = 1
x = 16/y
16/y - y = 1
16 - y^2 = y
y^2 + y -16 = 0
y = 3.53
so x = 4.53

4.53 and 4.53 to 2 decimal places

Answer 2

check: 3.53 * 4.53 = 15.9909 - close enough!
