I have test today​

Answer 1

Step-by-step explanation:

hence the answer is ,

a = -7 , b = - 12

Answer 2

Answer:

a= -7 b= -12

Step-by-step explanation:

$f(x) = {2x}^{3} + {3x}^{2} + ax + b$

given f(2) = 2

f(2) = 16+12+2a+b = 2

=> 2a+b+26 = 0 ------------- (1)

and f(-2) = -2

f(-2)= -16+12-2a+b = -2

=> 2a-b+2= 0 ------------- (2)

from eq (1)&(2), we get

a= -7

b= -12
