Put it into standered form first
\[\huge~\rm~ \bf ax^2+bx+c\]

@triciaal Why not?
jagr2713 (jagr2713):
Because x and x^2 are not the same :/
OpenStudy (triciaal):
x^2 is not the same as x
OpenStudy (triciaal):
like apples and bananas are both fruits but not the same fruit
OpenStudy (clamin):
do i factor this?
