<PRE><B>Question 927376</B>
xy = 24
y = x + 2
---
xy = 24
x(x + 2) = 24
xx + 2x - 24 = 0
---
the above quadratic equation is in standard form, with a=1, b=2 and c=-24
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
1 2 -24
into this solver: https://sooeet.com/math/quadratic-equation-solver.php
---
the quadratic has two real roots at:
---
x = 4
x = -6
---
using either root works fine for this problem:
x = 4
y = 6
OR
x = -6
y = -4
