Find the Values of the constants in the following indentities.
A(X^2 -1) + B(X - 1) + C = (3x -1)(x +1)
AX^2 - A + Bx - B + C = 3x^2 + 3x -x -1
Ok, Is this correct so far?
AX^2 = 3x^2 :. A = 3
Is correct ?
Bx = 3x = b = 3 ?
C = -1 ?
I'm sure this is wrong, I just need help explaining why and correcting my errors. It seems i need to simplify it more before comparing the co-efficients.
Thanks in advanced guys,
Probably all find this easy
