This type of question is very rare on Brainly. It's always a special occasion when one comes along. I call this a "twofer".
Wherever this question was copied from, it clearly had both a quadratic equation and a list of (4) methods along with it. Sadly, the individual who expects to be handed a fully-developed set of answers on a silver platter chose to share neither of them with the volunteers whose assistance he so earnestly solicits.
One might just as well come along and post:
<em>"Answer the following question, using the following words." </em>
and then leave it at that, for others to puzzle over.
