Step-by-step explanation:
some issues with the signa
Answer:
1 is the constant
Step-by-step explanation:
Answer:
Critical points are: 2 , -2 and 3.
Step-by-step explanation:
We have been given the expression:
![\frac{x^2-4}{x^2-5x+6}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E2-4%7D%7Bx%5E2-5x%2B6%7D%3C0)
We will factorize the given expression:
Using ![a^2-b^2=(a+b)(a-b)](https://tex.z-dn.net/?f=a%5E2-b%5E2%3D%28a%2Bb%29%28a-b%29)
![\frac{(x+2)(x-2)}{x^2-3x-2x+6}](https://tex.z-dn.net/?f=%5Cfrac%7B%28x%2B2%29%28x-2%29%7D%7Bx%5E2-3x-2x%2B6%7D%3C0)
![\Rightarrow \frac{(x+2)(x-2)}{x(x-3)-2(x-3)}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cfrac%7B%28x%2B2%29%28x-2%29%7D%7Bx%28x-3%29-2%28x-3%29%7D%3C0)
![\Rightarrow \frac{(x+2)(x-2)}{(x-2)(x+3)}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cfrac%7B%28x%2B2%29%28x-2%29%7D%7B%28x-2%29%28x%2B3%29%7D%3C0)
Critical point are those values of an expression when it is equal to zero
Hence, the critical points are: 2,-2 and -3.
Answer:
65 - 37 = s.
Step-by-step explanation:
Because s is the amount he needs to save, and he saved 37 dollars already. You need to subtract the two to get how much left.
