Question

can someone tell me if this problem is correct, list the possible rational roots?
f(x)=x^2+4x-5 ans: (x-1)(x+5)=x=1 x=-5
+-1,+-4,+-5=/1=+-1,+-4,+-5 ans:{1,-5

Answer 1

nope

Answer 2

possible roots are +1, -1, +5,-5

Answer 3

your answer for the actual roots are correct, but the possible rational roots are found by using the thm called the rational root theorem

Wink's solution is the correct one

do you need an explanation?

Answer 4

yes please

Answer 5

I'm trying to figure this out I have algebrator and algebra solved and I still cant figure it out

Answer 6

The rational root theorem is basically:

The real roots of an equation can be found by doing +- the constant term/ the leading coefficient
