Given that x^3 - 2x^2 + 3x - 2 = (x-1) (ax^2 + bx+c)
Determine a, b and c
I know the answers are 1, -1 and 2 but how do you get that?
thnx
Since (x-1) and (ax^2 - bx + c) are both factors, simply divide
by to determine (ax^2 - bx + c) and hence a, b, and c.You should get
, hence a=1, b=-1, c=2.If you wait a sec, I'll draw up an image showing the division.
