Question

if the zeros of f(x)= x cube -3 x squqre +x+1 are a-b , a , a+b find a and b and zeros​

Answer 1

Step-by-step explanation:

sum of roots = -(-3)/1 = a-b+a+a+b = 3a

so , a = 1

product of roots = -(1)/1 = a(a²- b²)

= 1(1 - b²)

so , 1-b² = -1

b² = 2

so the values of a,b are 1,±√2 respectively
