Best ResponseYou've already chosen the best response.0f/g means divide f's expression by g's

Best ResponseYou've already chosen the best response.0divide f(x) by g(x) and take out the point in which g(x) is zero. so domain will be real numbers  of that point

Best ResponseYou've already chosen the best response.0okay so like 20x^2 + 14x + 12 / 5x  6 That's what I thought it was initially, but not sure.

Best ResponseYou've already chosen the best response.0it might be easier to multiply g(x) by the choice and see if you get f(x) or, you can try dividing g(x) into f(x) of course, you need to know how to divide polynomials by another polynomial

Best ResponseYou've already chosen the best response.0yes you are going the right way... just be careful with the domain.

Best ResponseYou've already chosen the best response.0@lily1021 do you know how to divide polynomials?

Best ResponseYou've already chosen the best response.0if you learn anything in math, it is *no divide by zero* if there is an "x" value that makes the bottom zero , we do not allow x to be that number

Best ResponseYou've already chosen the best response.0@phi you are right

Best ResponseYou've already chosen the best response.0yes @phi if g(x) is zero then it wont be defined

Best ResponseYou've already chosen the best response.3But, do you know why you can never divide by 0 @lily1021 ?

Best ResponseYou've already chosen the best response.0i've divided polynomials before but i'm usually a hit or miss with them

Best ResponseYou've already chosen the best response.3Yes, that makes it "undefined."

Best ResponseYou've already chosen the best response.3Division by 0 has no meaning in the set of real numbers.

Best ResponseYou've already chosen the best response.0so I'm not going to divide then? Idk my heads spinning

Best ResponseYou've already chosen the best response.3Just like a word that has no meaning is undefined in the dictionary :)

Best ResponseYou've already chosen the best response.3Yes, first you divide one polynomial into the other.

skullpatrol

Best ResponseYou've already chosen the best response.3Second you set the divisor equal to 0 and find the values that make the divisor equal to 0 and exclude them in your answer.

Best ResponseYou've already chosen the best response.0I'm not sure why. You kinda just told me so I went with it if I'm being honest.
