I need help on math homework. Anybody who can help?

I need number 26,28,30

For 26 I got: fgh/x^2y

Flip the 2nd fraction, multiply straight across, then reduce.

If you can't do #26 then you'll need a lot of help with #28...

Umm... for #28 you should know a little bit about how to simplify, and also that when dividing one fraction by another, you can just flip one of them around and multiply.

For example 3/4 divided by 1/2 is the same as 3/4 multiplied by 2/1... change divide to multiply and flip 1/2 to 2/1

Yeah but there’s an easier way to reduce before you multiply across but I’m not good at it yet. The answers in the pic aren’t right btw

For #30 you have to know how to factor...

One process that I find easy is ask yourself what are all the ways to multiply to = 12

1 and 12
2 and 6
3 and 4

Then ask which of their pair adds to 7

That's a quick way to factor polynomials like the one in #30.

(n+4)(n+4) does not equal 16n^2

It equals n^2 + 8n + 16

On #28 it looks like you're crossing off the k that's part of k+3 but you're not allowed to do that.

Addition and subtraction sort of... "sticks" things together. You have to cross off the whole thing or none of it.

But when it's multiplied you can do only one. For example xy/x you can cross off an x from top and bottom.

But

x + y + 3 / x + y

you can't cross off anything.
