Question 930968: The difference between two whole numbers is 14. Their product is 1800. determine the two numbers

Answer by TimothyLamb(4379) (Show Source): You can put this solution on YOUR website!
x - y = 14
y = x - 14
xy = 1800
---
xy = 1800
x(x - 14) = 1800
xx - 14x - 1800 = 0
---
the above quadratic equation is in standard form, with a=1, b=-14 and c=-1800
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
1 -14 -1800
into this solver: https://sooeet.com/math/quadratic-equation-solver.php
---
the quadratic has two real roots at:
---
x = 50
x = -36
---
either root will work for this problem:
---
x = 50
y = x - 14
y = 50 - 14
y = 36
or
x = -36
y = x - 14
y = -36 - 14
y = -50
---
answer:
x = 50
y = 36
or
x = -36
y = -50
