3[m^2 - 5x + 30] 3[(m - 5/2)^2 +30 - 25/4] 3[(m-5/2)^2 + 120/4 - 25/4]
3(m-5/2)^2 + 95/4
Is that right?

| I have the inability to remember how to do math. I can do it one day, and have no idea what it is the next. |

Well I didn't see your amendment so I had to redo the whole thing changing 15x to 15m.
Simplification 3m2 + -15m + 90
Reordering 90 + -15m + 3m2
GFC (3): 3(30 + -5m + m2)
Answer== 3(30 + -5m + m2) |
