What are the roots of -12x^2+11x-3=0

Answer 1

you can complete the square or use the quadratic formula

Answer 2

do you know how to do either?

Answer 3

Yeah let me try the quadratic formula and see if i get the right answer

Answer 4

Yeah...idk how to do it.

Answer 5

\(ax^2+bx+c=0 \iff x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a} \)

for you

\[a=-12 \\ b=11\\c=-3\]

Answer 6

Yeah i got that ..but the answer choices have the letter i in them and idk where the i comes from

Answer 7

oh that is complex numbers used when you get negative square root

Answer 8

Would the answer be -11 plus or negative i×square root of 15 over 12?

Answer 9

I meant square root of 23 over 24

Answer 10

basically \[i = \sqrt{-1}\]

Answer 11

\[e.g.\sqrt{-11}=\sqrt{11}i\]

Answer 12

I understand thank you!
