Answer by josgarithmetic(39617) (Show Source): You can put this solution on YOUR website!
Ordered pair for the vertex is (0,5.3) because its x coordinate is in the middle of the zeros' values.

, full standard form

-
Solve for a

-
Substitute either of the given zeros to have an expression for a

which could really be expressed as a rational number, but if your 5.3 was a measurement
then a good choice could well be more like a=0.193.

a might in fact NOT be a repeating decimal in the way I thought first, but using , you should be able to find .
