Given: 4n³ + 3n² – 4n + k Find: Value of K Solution: ▢ (n – 1) = n = 1 ↬ 4 ༝ (1)³ + 3 ༝ (1)² – 4 ༝ 1 + k ↬ 4 + 3 – 4 + k ↬ 3 + k ↬ k = -3 Hence, the value of k is –3. Reply
4n³ + 3n² – 4n + k
12n² + 6n – 4
Given:
Find:
Solution:
▢ (n – 1) = n = 1
↬ 4 ༝ (1)³ + 3 ༝ (1)² – 4 ༝ 1 + k
↬ 4 + 3 – 4 + k
↬ 3 + k
↬ k = -3
