Is there any way to do this problem without trig?????

Yup... I am. Forgot to login.

this question does not have an answer on AoPS. Can someone please help me, I am stuck.

you better be sorry

1. use the formula of line of symetry to find x cordanite: -b/2a

2. When you find what -b/2a is, plug it into the formula

3. set the equation to zero and find the roots

4. since the parobla has max, it is (2.45, -infinity)

1. (1.7, 2.45)

2. x = 1.7

3. (1,0) and (2.4,0)

4. (2.45, negative infinity)

however the answer is wrong

thanks so much, Cphil
