What 2 numbers when multiplied equal 36 and when added equal -13?.
Hmmmm....how about -9 and -4
Group:
Factor out something common:
Voila!
2*x ^2 - 13*x + 18 = 0
So far I get :
General Term : a*x^2 + b*x + c
Which would be factored into :
(m*x + p) * ( n*x + q)
Where
m*n = a
p*q = c and
P*n + m*q = b
Step 1 -
m*n = 2
p*q = 18
P*n + m*q = -13
Step 2 -
Possible integer multiples
m n (and obverse)
2 = 1 & 2
Possible integer multiples
p q (and obverse)
18 = 1 & 18
2 & 9
3 & 6
So I get
(2*x + p)*(x + q) now I think I get a - 13 and an 18 so lets try
(2*x - 3) * (x - 6)
I now get lost help anyone. ...
