Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! x + y = 15
xy = 44
---
y = 15 - x
x(15 - x) = 44
15x - xx = 44
xx - 15x + 44 = 0
---
the above quadratic equation is in standard form, with a=1, b=-15 and c=44
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
1 -15 44
into this solver: https://sooeet.com/math/quadratic-equation-solver.php

the quadratic has two real roots at:
---
x = 11
x = 4
---
y = 15 - 11 = 4
y = 15 - 4 = 11
---
answer:
