Kimberly needs to solve the quadratic equation: x^2 + x – 2 = 2. which statement about how kimberly should solve this equation is true?

a. the quadratic formula is the only way to solve a quadratic equation.

b. the quadratic formula is a good method because this quadratic equation cannot be easily factored.

c. the quadratic formula is not a good method because you can factor the equation since -2 is divisible by 1.

d. kimberly cannot solve this quadratic equation because it is not set equal to 0.

B.The quadratic formula is a good method because this quadratic equation cannot be easily factored.

you just have to get 2 over to the left side of the equation.

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

it is b)

hope this : )
