Question

if x= 0 and x = -1 are the roots of the polyomial f(x) =2x power 3 - 3x power2 +ax+b

Answer 1

Answer:

ANSWER:

2X^3-3X^2+ax+b

1) when x=0

f(x)=2(0)^3-3(0)^2+a(0)+b

=0+b

b=0【given :root】

2) when x=-1,

f(x)=2(-1)^3-3(-1)^2+a(-1)+b

= -2-3-a+b

0 = -5-a+b

b= -5-a+b

Step-by-step explanation:

a=-5

substitute" a" value u will get b

value

try ur self u will get the answer and then tell me (^_^)(^_^)(^_-)
