Question 8
PolynomialsGiven that (8x + m)/(x2 − 3x − 4) ≡ 5/(x + 1) + 3/(x − 4), find the value of m.
- A.23
- B.17
- C.−17
- D.−23
Show the answer and explanation
Answer: C (−17)
Explanation
8x + m = 5(x − 4) + 3(x + 1) = 8x − 17, so m = −17.
Given that (8x + m)/(x2 − 3x − 4) ≡ 5/(x + 1) + 3/(x − 4), find the value of m.
Answer: C (−17)
8x + m = 5(x − 4) + 3(x + 1) = 8x − 17, so m = −17.
