Question

If x=0 and x= (-1) are the roots of the equation p(x) =(2x) cube - (3x) square +ax+b.Find A and B​

Answer 1

Step-by-step explanation:

given roots (0,-1)

Given

p(x)=(2x)^3-(3x)^2+ax+b

then

p(0)=(2×0)-(3×0)+(a×0)+b=b=0

p(-1)=(2×-1)^3-(3×-1)^2+(a×-1)+b=-8-9-a+b=0

from those two

as b=0

from 2nd

a=-17
