Question 220355: Please help me solve this equation:
Find the maximum or minimum value
f(x)= 3(x+10)(x-8)
I tried doing this..
x intercepts= -10 and 8, so (-10+8) /2= -1
But when I plugged -1 in for x and I came out with the minimum as -243, but that just seems to ridiculous as an answer..

It looks right to me!! In math, you get a lot of UGLY answers--so many that you just have to get used to it!!
