This question was answered by Cphill before

 

This is what he answered

 

What real value of t produces the smallest value of the quadratic t^2 -9t - 36

 

Since this is  an upwards-turning parabola, the "t" that produces the smallest possible value  is given by :

 

-b/ [2a] =  -[9] / [2 (1) ] =   9/2 = 4.5
