: I got some problems i need help with please.
: Simplify each rational expression
: 1/5 over 5/18 1/5/5/18
1/5 over 5/18
= (1/5)/(5/18)
=1/5 * 18/5
= 18/25 Please review your "pre-algebra" work -specially manipulating fractions. You need to learn that thoroughly before you can jump into algebra.
I really hate to say this - but - if you could not do the problem above, you are NOT ready to do the rest of the problems.
: multiply
: x^2+10x+21/x^2+15x+56 times x^2+8x/x^2+9x+18
: use the quotient rule to simplify
: square root of 144x^4 over the square root of 6x
: find all numbers that must be excluded from the domain of each expression.
: x^3+4x^4 over x^2+36

: thanks
