I need to solve 4 equations, using a different method for each, and using the method that works the best for each particular equation. (quadratic formula, completing the square, factoring, and graphing)
here are the equations:
1) x² -24=10x
2) 3x² + 26x + 55 =0
3) 2x² =5x + 7
4) x² - 6x - 11 =0
I don't need help solving, I'd just like to know which certain method makes best sense for each problem (1-4).

I’m stuck on this equation, anyone got the answer?

Create a graph for the demand for starfish using the following data table: quantity/price of starfish quantity (x axis) of starfish in dozens price (y axis) of starfish per dozen 0 8 2 6 3 5 5 2 7 1 9 0 is the relationship between the price of starfish and the quantity demanded inverse or direct? why? how many dozens of starfish are demanded at a price of five? calculate the slope of the line between the prices of 6 (quantity of 2) and 1 (quantity of 7) per dozen. describe the line when there is a direct relationship between price and quantity.

Use sigma notation to represent the following series for 9 terms.
