Question

Simplify and select the answer with the appropriate restrictions for the variables.

(x+4)(x+2) / 4x+8

Answers:

1. X+2/4 (x= -2)
2. x+4/4 (x = -2)
3. 4/x+4 (x =-4)
4. 4/x+2 (x = -2)

Answer 1

ok so to simplify this you need to factor the bottom of the given equation:
(x+4)(x+2) / 4x+8 --> (x+4)(x+2)/4(x+2)
Now you can cancel out x+2 on the top and bottom.
You are now left with x+4/4

Answer 2

(your answer is 2)

Answer 3

thank you! Would you mind helping with a couple more?

Answer 4

sure

Answer 5

Simplify and select the answer with the appropriate restrictions for the variables.


2x-3x^2/5x^3

That's the next one, i'll get you the answers

Answer 6

1. 1/5
2. 1/5x (x = 0)
3. 1/5x^2 (x = 0)
4. 2-3x/5x^2 (x = 0)

Answer 7

ok so the top of this equation is factored out to be: -x(3x-2)
the bottom of this equation cannot be factored. x does= 0

Answer 8

So that means answer one would be taken out of the possibilities. But there's three left and nothing else can be factored out of it?

Answer 9

Nevermind, i got it.
