German Language, but I forgot how I can tell when I can use the pq formula cause sometimes I could read do it to get the 0 points or whatever they’re called

German Language, but I forgot how I can tell when I can use the pq formula cause...
pq formula works when you have a plain x² + px + q = 0
that's the condition
ionic hazel
always factor out x first when u can, pq only comes in when you are left with a monic quadratic that doesn't factor cleanly
haughty atlas
Do you see a function where p and q is already given?
Or the 0 numbers
0 places or something
Do I’ve to multiply a out or
ionic hazel
for example a. x^2-12x+35 p=-12, q=35 --> x = 6 +- 1 and it zeros at 5 and 7
in b. don't use pq, just factor
haughty atlas
Ahh I see if the following numbers font have x^2?
sudden musk
wait are the examples just factoring or something else?

Bin formel

Factoring only lol
It’s pretty easy I had in 9. grade but forgot zheprincip a bit
ionic hazel
Ahh I see if the following numbers font have x^2?
yes if it's x^2 + smthx + smth the coefficient on x is p and the last number is q
sudden musk
if u have x^2 - y ^2 it is equal to (x-y)(x+y)
ionic hazel
if there is no x^2 or the x^2 has a number in front u just sort that out first
haughty atlas
for example a. x^2-12x+35 p=-12, q=35 --> x = 6 +- 1 and it zeros at 5 and 7
-7 Right?
haughty atlas
if there is no x^2 or the x^2 has a number in front u just sort that out first
Oh okay okay
What about d?

np
ionic hazel
yup
