-4.9x^2+24x+2=0

x=(-24+-sqrt[24^2-4*-4.9*2])/2*-4.9
x=(-24+-sqrt[576+39.2])/-9.8
x=(-24+-sqrt[615.2)/-9.8
x=(-24+-24.8)/-9.8
x=(-24+24.8)/-9.8
x=.8/-9.8
x=-.08 ans.
x=(-24-24.8)/-9.8
x=-48.8/-9.8
x=4.98 ans.

how to factor -4.9x^2+24x+2=0
---------------
Use the quadratic formula:
---
x = [-24 +- sqrt(24^2 - 4*-4.9*2)]/(-9.8)
---
x = [-24 +- sqrt(615.2)]/-9.8
---
x = [-24 +- 24.803]/-9.8
---
x = -0.803/-9.8 or x = -48/-9.8
------------------------------------
x = 0.08196 or x = 4.898
------
(x-0.08196)(x-4.898)
