Question

x^3-5x^2-66x=0

Answer 1

does it really say \(x^3-5x-66x=0\)?

Answer 2

yeah

Answer 3

so i guess it is really
\[x^3-71x=0\]

Answer 4

oh wait 5x^2
sorry

Answer 5

\[x^3-5x^2-66x=0\]

Answer 6

start with \[x(x^2-5x-66)=0\] one solution is obviously \(x=0\) to find the others solve
\[x^2-5x-66=0\] by the quadratic formula, or factoring if you think it factors

Answer 7

by some miracle this one does factor as
\[x^2-5x-66=0\]
\[(x-11)(x+6)=0\]and then you should be good to go

Answer 8

Thank you so much (:
