Hey there!
When finding the difference of expressions like these, there's a few things you should keep in mind.
1. When finding the difference of two polynomials, multiply the polynomial that implied to be "negative" by –1 to expand the problem and make it easier to solve.
2. You combine terms based on their unknown terms, like x, y, x², ab, etc. You cannot combine the terms x and x², but you can combine the terms 6b and 8b by adding them.
3. You can rearrange your terms however you see fit. If a polynomial is implied as "positive", you can multiply that entire polynomial by +1 to get rid of the parentheses.
With all that in mind, you can go ahead and solve for your difference, like so:
![(ab+8a+1)-(-6ab+4)](https://tex.z-dn.net/?f=%28ab%2B8a%2B1%29-%28-6ab%2B4%29)
![(ab+8a+1) (-1(-6ab+4))](https://tex.z-dn.net/?f=%28ab%2B8a%2B1%29%20%28-1%28-6ab%2B4%29%29)
![(ab+8a+1) + (6ab-4)](https://tex.z-dn.net/?f=%28ab%2B8a%2B1%29%20%2B%20%286ab-4%29)
![ab+6ab+8a+1-4](https://tex.z-dn.net/?f=ab%2B6ab%2B8a%2B1-4)
![7ab+8a-3](https://tex.z-dn.net/?f=7ab%2B8a-3)
![7ab+8a-3](https://tex.z-dn.net/?f=7ab%2B8a-3)
will be your difference.
Hope this helped you out! :-)
Answer:
x-intercepts: (2, 0) and (−5, 0)
y-intercept: (0, −10)
Step-by-step explanation:
y = x^2 + 3x − 10
y-intercept when x = 0 so y = -10, so y-intercept : (0, -10))
x-intercept when y = 0 so
x^2 + 3x − 10 = 0
(x +5)(x - 2) = 0
x + 5 = 0; x = -5
x - 2 = 0; x = 2
So x-intercepts: (-5, 0) and (2,0)

Answer: 25:15
Step-by-step explanation: in the ratio 5:3 the 5 is dogs and the 3 is cats you multiply the 5 (aka the dogs) by 5 to get 25 (the amount of dogs in the shelter) when you multiply 3 by 5 you get the amount of cats which is 15, a good way to remember is what you do to one side you have to do to the other. I hope this helps.
