This is a bowl shaped parabola due to the positive coeffecient of the xterm

    the minumum will occur at   t = - b/2a   =  -  -9/2 =   9/2    This is the real value which produces the minumum value of the quadratice

       IF you want that minumum value:

                           use this value of 't' in the equation to calculate the minumum value of the quadratic .....
