Answer 1

Answer:hey here is ur answer

x-1 and x+1

by using a2-b2=x2-root1

=x2-1 then by factorizing u will get two zeroes x=1,x=-1

Put x= -1,1 to find a and b

First,put x = 1

ax³+x²-2x+b = 0

a(1)³+(1)²-2(1)+b=0

a+1-2+b=0

a+b-1 = 0

a+b = 1 first equation

Put x = -1

a(-1)³+(-1)²-2(-1)+b = 0

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

-a+b+3 = 0

-a+b = -3 second equation

from 1 and 2 we get

a+b = 1

-a+b=-3

-----------

2b = -2

b = -2/2

b = -1

Put b= -1 in (1)

a+(-1) = 1

a-1 = 1

a=1+1

a=2

Therefore, a = 2 and b = -1
