Do the math

2 * (x-3)(x+6) = 2x^2 +6x-36    this in upward shaped parabola (like a bowl)

minimum x value will be    - b/(2a)    -6/4       use this value to calculate the y value from the original equation....

Please do not discuss this problem! This is an active homework problem. To the original poster: I realize that homework may be challenging. If you wish to receive some help from the staff or other students, I encourage you to use the resources that the online classes provide, such as the Message Board. Thanks.
