Find the maximum value of the expression 1x2+5x+10
The correct option is B 415
For the given expression to have the maximum value, the denominator should be minimized. (Since the function in the denominator has imaginary roots and is always positive). x2 + 5x + 10 will be minimized at x = -2.5 and its minimum values at x = -2.5 is 3.75.
Hence required answer = =13.75=415
