\[x^2+17x+30\]

Answer 2

ok , so u need two numbers that there sum is 17 and there multiplicatin is 30 :D
what do u think ?

Answer 3

Umm Same numbers for each. Right?

Answer 4

mmm not really
its like a guessing game :)
first find two numbers a,b
such that ab=30

Answer 5

Well. I have all the factors of 30 but none of them equal 17.

Answer 6

no no
ok 30 =30*1
but 30+1=31

30=6*5
but 6+5 =11

30=3 * 10
but
3+10

30=15*2
15+2=17

see we need the sum of factors =17
not the factors them selves , got it now :o

Answer 16

What about this kind?
\[x^2-13x+36\]
I know it's 4 and 9. Not sure which ones negative though.

36=4*9
and
4+9=13

4+9\(\neq -13\)
-4+9\(\neq -13\)
4-9\(\neq -13\)
-4-9\(=- 13\)
