What are the solutions to this quadratic equation? -2x^2+x+4=0

Step-by-step explanation:

note : -2x²+x+4=0      quadratic equation when : a= -2   b=1   c=4

delta = b² - 4ac

delta =  (1)² - 4(-2)(4) =33

X1 = (-b+sqrt(delta))/2a

X2 = (-b+sqrt(delta))/2a continue

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
