Question

how do i simplify this?

Answer 1

Can you factor the top and bottom expressions? Are you missing an x in that top expression?

Answer 2

Or is it \[x^2-10+9=x^2-1\]?

Answer 3

im supposed to simplify it.

Answer 4

It makes a difference because \[x^2-10+9=x^2-1 = (x-1)(x+1)\]but \[x^2-10x+9=(x-1)(x-9)\] Which one is the correct expression?

Answer 5

What are the factors for \[x^2+2x-3=?\]

Answer 6

Do you know how to factor? For the expression in the denominator we know\[x^2+2x-3=(x+a)(x+b)\]where a and b are integers that must solve\[a+b=2 \text{ and } ab=-3\]
