I have a few questions I need help with:

1. Can 2 different quadratic formulas have the same roots? Explain why or why not.

2. Write the vertex form of (x-6)(x+2)

3. Write x³+x²-6x in factor form

4. For these questions the answer on the right are incorrect, I need the correct answer written in the original form of the answer on the right.

x²+5x-24=(x+3)(x-8)

(x+2)(x-5)=x²-10

(x+3)²=x²+5

Thanks for the help in advance!
