Answer :
∵ 0 and 1 are the zeroes of the polynomial f(x) = 2x3-3x2+ ax + b
∴ f(0) = 0 and f(1) = 1
Now,
f(x) = 2x3-3x2+ ax + b
⇒ f(0) = 2(0)3 – 3(0)2+ a(0) + 0
⇒ 2 × 0– 3 × 0 + a × 0 + b = 0
⇒ 0– 0 + 0 + b = 0
⇒ b = 0
And,
⇒ f(1) = 2(1)3 – 3(1)2+ a(1) +1
⇒ 2 × 1– 3 × 1 + a × 1 + b = 0
⇒ 2– 3 + a + b = 0
⇒ 2– 3 + a + 0 = 0 [∵ b = 0]
⇒ -1 + a = 0
⇒ a = 1
