Consider the polynomial f(x)=17x4+21x3+60x2+Ax+B. Suppose that for every root λ of f(x)=0, 1λ is also a root of f(x)=0. What is the value of A+B?

• maths -

what is 1λ ?
A missing symbol somewhere?

1/λ?
1-λ?
1+λ?

• maths -

actually it's 1/λ

haha this is a feautured problem on Brilliants :')

Yes ... ! :P LOL
