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).

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 104 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 105 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.

Which undefined geometric term is described as a location on a coordinate plane that is designed by an ordered pair (x,y) ?
