what value of x would the quotient (2x^2 + 3x - 4) ÷ (x + 4) not make sense?

Question

terenzreignz · Answer

Surely, when divisor is zero? :)
The divisor is x + 4, so for what value of x would this be equal to zero?

anonymous · Answer

i think so in order for the (2x^2 + 3x - 4) to make since right ?

terenzreignz · Answer

Wait what?
LOL
I just asked you for what value of x would the divisor (x + 4) be equal to zero :P

x + 4 = 0
solve for x...

anonymous · Answer

lol oh -4

terenzreignz · Answer

mhmm... so when x = -4, then the divisor becomes
(-4 + 4) which is zero...

and you know you can't divide by zero ;)

anonymous · Answer

yea so is x=-4

terenzreignz · Answer

That's it :)

anonymous · Answer

ok do i do the same process each time for questions like this

terenzreignz · Answer

Pretty much...
If you're asked for what values of x would the division not make sense, always check for values of x which would make the denominator equal to zero... :)

terenzreignz · Answer

^Because dividing by zero... doesn't make sense LOL

ok Thanks So much !
