Question

Rational Expressions.

1.) 2x^2-8x 8x^2
_______ / ____
x^2-16 (x+4)^2

Solution: x+4
___
x

Is this correct?

Answer 1

Sorry that came out a bit messier than I had intended. It should read 2x squared minus 8x over x squared minus 16, divided by 8x squared over (x+4)squared.

Answer 2

Spaces can't be handled on the board. The best way to write a problem is to use parentheses. For example,
x-2 divided by 3 + 4 divided by x and the 4 divided by x is squared.
[(x-2)/3] + (4/x)^2 = etc.

Answer 3

Haha thanks, I learned the hard way but now I know.
