EXPLANATION.
0 and 1 are the zeroes of the polynomial,
⇒ f(x) = 2x³ - 3x² + ax + b.
As we know that,
⇒ F(x) = 0.
Put the value of f(x) = 0 in equation, we get.
⇒ f(x) = 2x³ - 3x² + ax + b.
⇒ f(0) = 2(0)³ - 3(0)² + a(0) + b = 0.
⇒ 0 - 0 + 0 + b = 0.
⇒ b = 0.
As we know that,
⇒ F(x) = 1.
Put the value of f(x) = 1 in equation, we get.
⇒ F(x) = 2x³ - 3x² + ax + b.
⇒ 2(1)³ - 3(1)² + a(1) + b = 0.
⇒ 2 - 3 + a + b = 0.
⇒ -1 + a + b = 0.
⇒ a + b = 1.
Put the value of b = 0 in equation, we get.
⇒ a + 0 = 1.
⇒ a = 1.
Values of A = 1 & B = 0.
