Question

10m^2+2m-3=0

use the quadratic formula

Answer 1

i wanna make sure i did it correct

Answer 2

plug and chug.
\[x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\]

Answer 3

ok we get
a = 10
b = 2
c = -3

Answer 4

best to write them down and then you know what you are substituting

Answer 5

less likely to screw up

Answer 6

What is the answer you got? We can tell you if its right or not, This is the 5th one of these ive seen from you :P maybe we can teach you instead of give answers. Again, it is in standard form of \[ax^2 + bx + c = 0\] now, just plug and chug into the quadratic equation :)

Answer 7

\[\frac{-2\pm\sqrt{2^2-4\times 10\times -3}}{2\times 10}\]

Answer 8

ok so -2+- square root 2^2-4(2)(-3)/2(10)

Answer 9

i get
\[\frac{-1\pm\sqrt{31}}{10}\]

Answer 10

oh wait i am sorry you are right

Answer 11

you are correct.

Answer 12

\[-2\pm \sqrt{28}\]/20

Answer 13

get
\[\frac{-2\pm\sqrt{124}}{20}\]

Answer 14

think you messed up with
\[b^2-4ac\] again

Answer 15

\[2^2-4\times 10\times -3\] two minus signs so it is plus

Answer 16

\[4+120\]

Answer 17

124

Answer 18

-2 +- square root 124/20
