For any parabola of the form \(ax^2+bx+c=0 \) the vertex will be at \( \large \left(\frac b {2a} , \frac {b^24ac}{4a}\right) \).Equation of line of symmetry will be at \(x=\frac b {2a} \) Maximum and minimum values will be at \( \large \left(\frac b {2a} , \frac {b^24ac}{4a}\right) \) and \( \large \left(\frac b {2a} , \frac {b^24ac}{4a}\right) \) for \(a<0\) and \(a>0\) respectively.

can we do this like : 45x4x^2 44(x^2+5x/4) 44(x^2+5x4 +25/64) + 25/16 ?

just maximum value

44(x^2+5x4 +25/64) + 25/16 89/164((x+5/8)^2) hence it as min. value of 89/16 at x =5/8 is it right ?

every x you get i will pick one,that that my function will be less than yours

Yes, for every minimum you find I can find another x which gives a lesser value ...
