Question

Determine the equation whose roots are -1,-5, and -3

Answer 1

Roots of an equation mean places where f(x) = 0. You remember how to find the solutions of a quadratic equation by factoring, right?

Answer 2

um kinda but not really

Answer 3

The point is if you remember how the solution always ends up looking.
\[(x - a)(x - b)\]

Answer 4

oh yes!

Answer 5

So if there are three roots... how will that look? :D

Answer 6

(-1--5) (-1--3)... right?

Answer 7

No.. it's going to be in the form of \((x - a)\) terms.

Answer 8

The solution of \(x - a\) = 0 is just a.
The solutions of \((x-a)(x-b)\) = 0 are a and b...
And so on.

Answer 9

oh ok
