Question

if the zeros of the polynomial x^3 - 3x^2 +2 are a-b , a & a+b, then the values of a and b are? pls help....... it's very urgent

Answer 1

here is your answer.....
a-b+a+a+b=-(-3)/1
=}3a=3
={a=3/3
=}a=1


then, product of zeroes
(a-b)(a)(a+b)=-2/1

(1-b)(1)(1+b)=-2/1
1-b²=-2
-b²=-2-1
-b²=-3
b²=3
b=±√3
that's all...
