Answer 2

Answer:

b = -3, a= 3

Step-by-step explanation:

f(x) = x^4+ ax³+ 2x²- 3x+b

1 and -1 is the zeroes of the polynomial,

Put x = 1 and x=-1 to find the value of a and b

f(1) = (1)^4+ a(1)³+ 2(1)²- 3(1)+b = 0

or, 1+a+2-3+b = 0

a+b = 0

a= -b.................i

f(-1) = (-1)^4+ a(-1)³+ 2(-1)²- 3(-1)+b = 0

1 - a +2+3+b = 0

b-a = -6.......................ii

Put i on ii

b-(-b) = -6

2 b = -6

b= -6/2

b = -3

a= 3
