Best ResponseYou've already chosen the best response.0I have already found x=6 and x=4, but that was somehow wrong. Is one of these invalid for some reason?

Best ResponseYou've already chosen the best response.0the x = 4 is correct, the other x intercept however is x = 0 :)

Best ResponseYou've already chosen the best response.0@plohrb why isn't x=6 correct?

Best ResponseYou've already chosen the best response.1guess what i guess you factored ot the quadratic equations right ? we have to find two numbers when we multiply them we should get `product of AC`(a = leading coefficient , c= constant term) when we add or subtract them we should get the middle term

Best ResponseYou've already chosen the best response.0I set the numerator equal to 0, is that wrong?

Best ResponseYou've already chosen the best response.16 times 4 = 24 \(\checkmark\) 6+4 isn't positive 2

Best ResponseYou've already chosen the best response.0youre supposed to set the y equal to 0, not the numerator

Best ResponseYou've already chosen the best response.1xintercepts a point where graph intersect xaxis when y = 0 so substitute y for 0 find factors of the numerator and denominator

Best ResponseYou've already chosen the best response.0if you set y equal to 0 then the denominator ends up getting multiplied by 0 anyways so its the same thing as setting the numerator to 0

Best ResponseYou've already chosen the best response.1if you multiply denominator by 0 then answer would be undefined anything times 0 would be 0 and you can't divide by 0
