Answer 1

Answer:

Step-by-step explanation:

If x = 0 & x= -1

f ( x ) = 2x³ - 3x² + ax + b

Put 0 in place of x ,

f ( 0 ) = 2 (0)³ - 3 (0)² + a × 0 + b

= 2 × 0 - 3 × 0 + 0 + b = 0

= 0 - 0 + b = 0

= b = 0

Now put x = - 1

f ( - 1 ) = 2 ( - 1 )³ - 3 ( - 1 )² + a ( - 1 ) + 0

= 2 × - 1 - 3 × 1 - a + 0 = - 1

= - 2 - 3 - a = - 1

= - 5 - a = - 1

= - a = - 1 + 5

= a = - 4
