I've studied so much for Calculus, I forgot how to algebra

I need halp, how do? I factored it and then had no idea what to do.

x 2 +13x+40 divided by x 2 +17x+72 all multiplied by x 2 +9x over x 2 -3x-40

This is how I factored it

(x+5)(x+8)( x 2 +9x)

over

(x+9)(x+8)(x-8)(x+5)

Which I then reduced to

x 2 +9x

over

(x+9)(x-8)

Of the four answers. One is like mine, but without the (x+9) and two others have just an x on top and the last answer just has a one on top. So what gives?

If you got (x^2+9x)/((x+9)*(x-8)), how can you reduce it further?

Factor an x out of your last step to make it x(x+9) over (x-8)(x+9) then cancel the (x+9) to leave you with the answer.

Holy fuck I’ve forgotten algebra.

I never learned it in the first place. As a musician, I only have to be able to count to three.

No problem, I am not a math teacher but I play one on TV....

I wish I was on TV the pay would be better....

What happened to my he whole numbers? Shouldn’t there be a 72 in there somewhere to give you the other side of the equation?

There’s no other side of the equation. It’s just two fractions multiplied together. It was just factoring. Phryxes got the right answer. I just had to factor after my factoring.

Gotcha, it’s been awhile for me too for all the maths.
