When you ask "what do you add to A to get B, you solve it by subtracting.
For example, what do you add to 5 to get 13?
Subtract 13 - 5 = 8
The answer is you add 8 to 5 to get 13.

Now you need to do the same with your polynomials.
What do you add to <span>x^2 - 2x + 6 to get 3x^2 + 7x?

To find the answer, subtract

(3x^2 + 7x</span>) - (x^2 - 2x + 6)

What is the domain of the function f(x) = x + 1/ x^2 - 6 + 8?
dangina [55]

Answer:

The domain is all values but x=4 and x=2

Step-by-step explanation:

f(x) = (x+1) / ( x^2-6x+8)

Factor the function

f(x) = (x+1) / ( (x-4) ( x-2))

The domain of the function is all values of x except where the function does not exist

This is where the denominator goes to zero

(x-4) ( x-2) =0

Using the zero product property

x-4 =0   x-2 =0

x=4   x=2

The domain is all values but x=4 and x=2

Artyom0805 [142]
2 1/2 is in mixed fraction. So let's first make it into improper fraction.

(2*2 + 1) / 2 = 5/2

5/2 of 7.25 = (5*7.25) / 2 = 18.125 

in short, 18.125 is the answer
