Question

please help

What is a polynomial with a single root at x = -6 and a double root at x = -3?

Answer 1

If one root is x= -6, you get a polynomial (x+6)
Then the double root gives you (x+3)

Answer 2

@Gebooors so (x+6)(x+3) ?

Answer 3

Because of double root, try (x-3)^2

Answer 4

I meant (x+6)(x+3)^2

Answer 5

x3+12x2+45x+54 @Gebooors I got this

Answer 6

Good work!

Answer 7
