Question

Use the Quadratic Formula to solve the equation.
6 + 6x – x^2 = 0

Answer 1

i got an answer involving a square root and got it wrong :(

Answer 2

\[x=\frac{-6\pm \sqrt{6^2-4(-1)(6)}}{-2}\]

Answer 3

after that i got (-6+-√60)/2

Answer 4

do you think the final answer should be (-6+-2√15)/2

Answer 5

\[x=\frac{-6\pm \sqrt{60}}{-2}\]

Answer 6

\[x=\frac{-6\pm2\sqrt{15}}{-2}\]

Answer 7

should i divide the 6 by 2?

Answer 8

-6/-2?

Answer 9

\[x=3\pm \sqrt{15}\]

Answer 10

i was under the impression i was not to touch the number that is next to the radical if it is not seperated by a +- sign

Answer 11

You have two terms in the numerator. They can be reduced individually

Answer 12

oo ok, thanks for your help

Answer 13

\[x=\frac{-6}{-2}\pm\frac{2\sqrt{15}}{-2}\]
