If (x+1) i the HCF of Ax²+Bx+C and Bx²+Ax+C where A ≠ B, then the value of C is
Elementary MathematicsRatio and Proportion
- AA
- BB
- CA - B
- D0
Explanation
Since (x + 1) is a common factor, x = -1 is a common root: A - B + C = 0 and B - A + C = 0. Adding gives 2C = 0, so C = 0. Hence option (d).
