Homework Help: Algebra II

Posted by Lucy on Saturday, February 23, 2008 at 5:11pm.

The question simply states-solve.

-x^4+200=102x^2

I rearranged the equation so that I have x^-102x^2+200=0

Since I cannot factor this my solution is x= -51 =/-2 square root of 2801 divided by 2. Is this correct.

Also a second problem that I do not know how to work is this:
The shape of a supporting arch can be modeled by h(x)=-0.03x^2+3x, where h(x) represents the height of the arch and x represents the height of the arch and x represents the horizontal distance from one end of the base tothe arch in meters. Find the maximum height if the arch.

Any help on how to start this problem would be helpful.

Thanks.
