f(x) = 2 x 3 − 3 x 2 + ax + b ∵ x = 0 and x = - 1 are its zeros ∴ f (0) = 0 and f(-1) = 0 Now, f(0) = 0 ⇒ 2 ( 0 ) 3 − 3 ( 0 ) 2 + a × 0 + b = 0 ⇒ 0 - 0 + 0 + b = 0 ∴ b = 0 and f(-1) = 0 ⇒ 2 ( − 2 ) 3 − 3 ( − 1 ) 2 + a (-1) + b = 0 ⇒ 2 × ( − 1 ) − 3 × 1 + a × (-1) + b = 0 ⇒ -2 - 3 - a + b =0 ⇒ − 2 − 3 − a = 0 ⇒ a = - 5 ⇒ − 5 − a = 0 ⇒ a = - 5 Hence a = - 5, b = 0
