You can put this solution on YOUR website! x^2 + 22x + 120 = 0
---
the above quadratic equation is in standard form, with a=1, b=22 and c=120
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
1 22 120
into this solver: https://sooeet.com/math/quadratic-equation-solver.php
---
the quadratic has two real roots at:
---
x = -10
x = -12
---
(x + 10)(x + 12)
---
you can also factor it by observation:
find two factors of 120 that when added together equal 22:
---
120 = 2*60 = 4*30 = 8*15 = 10*12
---
10 and 12 fit the bill: 10+12=22
---
answer by observation:
(x + 10)(x + 12)
