is the question

Answer 2

Answer:

Since, x+1 is a factor of p(x)=2x 3 +ax 2 +2bx+1 Then, by factor theorem, p(−1)=0 ⇒−2+a−2b+1=0⇒a−2b=1 ...(i) Also,2a−3b=4 ...(ii) On multiplying (i) by 2 and (ii) by 1, we get 2a−4b=2 − 2 ​ a + − ​ 3b= − 4 ​ ​ −b=−2 ∴b=2 On putting b=2 in (i), we get a−2×2=1⇒a=5 ∴a=5,b=2y.
