Solved Find the absolute minimum value of the given function

WebTherefore if 2a<0 then the polynomial has a maximum at x= 2a−b. and if 2a>0 then the polynomial has a minimum at x= 2a−b. Consider the given polynomial 2x 2+x−1. a=2, b=1,c=-1. Hence a>0, so at x= 2a−b the given polynomial will have a minimum from i and ii. 2a−b= 4−1. Substituting in the quadratic polynomial we get.
