Its f(x) subtraction is the opposite of addition so you have to subtract (f-g)(x)-g(x) and if you multiply (f-g)(x) then it would be f(x) because a number times x or x by itself is x and if it was 4(x) it would be 4x parantheses means to multiply. Hope this helps!!!

Simplify completely<br> x2 + 4x - 45<br> and find the restrictions on the variable.
malfutka [58]

Answer:

(x-5)/(x+1) and x cannot equal -1 because the denominator can't be zero.

Step-by-step explanation:

Factor the numerator:

(x+9)(x-5)

Factor the denominator:

(x+1)(x+9)

So you have

(x+9)(x-5)/(x+1)(x+9); see that you can cross out the (x+9) in both the numerator and denominator?

You're left with (x-5)/(x+1)

The only number that is restricted is -1, because that would make the denominator zero, which is a no no!!
