What is the minimum value of 5x^2 - 20x + 1357 - 80x + 415?
5x^2 - 20x + 1357 - 80x + 415 = 0
5x2 -100x + 1772 = 0 Bowl shaped parabola ... minumum value of the function will occur at the x value = - b/2a = - -100/10 = 10
use this value of 'x' in the equation to compute the minimum value of the fxn.
