Question

What polynomial has roots of -4, -1, and 6?

Answer 1

x3 - 9x2 - 22x + 24

x3 - x2 - 26x - 24

x3 + x2 - 26x + 24

x3 + 9x2 + 14x - 24

Answer 2

the polynomial for the following roots is
(x+4)(x+1)(x-6)

Answer 3

i got x3-2x-26x-24

Answer 4

What is a root? It's simply when the polynomial is zero.

So if -4 is a root then that means if you plug in x=-4 we should get zero. So (x+4) will be part of what we need, since zero times anything else is zero, it sort of brings the rest of the equation with it.

Or you could apply theory of equations for fun , forget it if you don't know it , Just saying another method to solve this
