QUADRATICS 2


Find the maximum value of the quadratic equation:3-2t-10t2.

Solution

a=-10, b=-2, c=3

Maximum = 4ac-b2
                        4a

Maximum = (4 x -10 x 3) - (-2)2
                          4(-10)

Maximum = (-120)- 4
                         -40

Maximum=  -124
                      40

Maximum = -31
                     10
Hence maximum value is -31/10
