Question

use the quadratic formula to solve the equation -4x^2-3x+2=0

Answer 1

using the quadratic formula amounts to inputting the values it asks ... then working the basic math

what part are you stuck on?

Answer 2

please show work!

Answer 3

I think im just confused on how to actually solve the problem after i input the values

Answer 4

show me how you inputed the values then. then i should be able to determine how to proceed

Answer 5

im not sure how to type the formula on this thing this is my first time on here

Answer 6

ascii wirks just fine

-b +- sqrt(b^2 -4ac)
------------------
2a

Answer 7

ok i will try

Answer 8

so a = -4, b= -3 and c= 2 ? so now i put it into the equation?

Answer 9

yes, you would insert those values into the "formula" to find the solutions

Answer 10

-b +- sqrt(b^2 -4ac)
------------------
2a


-(-3) +- sqrt((-3)^2 -4(-4)(2))
--------------------------
2(-4)


3 +- sqrt( 9 +32 )
----------------
-8


3 +- sqrt(41)
- ------------
8

Answer 11

ok yah i was just typing that, so its 3/8 +-sqrt (41/8) ?

Answer 12

Answer 13

-3/8 +- .... if i see it right

Answer 14

yeah :)

Answer 15

ok yes thank you so much! you made it a lot easier to understand than my teacher lol! thx!

might be a typo, but make sure you dont include
that 8 into the sqrt

Answer 17

3/8 +-sqrt (41)/8

Answer 18

ugh, forgot the - again

Answer 19

ohhh ok i see! thanks yeah sorry about that!

Answer 20

good luck ;)
