Question

A solution to the equation x2 – 9x – 22 = 0?

Answer 1

do you know how to factor out \(x^2 - 9x -22\)?

Answer 2

Yes. Is the answer -11?

Answer 3

no..what was your factored form?

Answer 4

9x+2(x)+1=0 (To solve for x) x= - 1/11. X= negative one over eleven.

Answer 5

\[x^2 – 9x – 22 = 0\]
\[d=b^2-4ac\]
\[d=(9)^2-4(1)(-22)\]
\[d=81+88=169\]

Therefore,
\[x=(-b \pm \sqrt{b^2-4ac})/2a\]
Putting the valuen we get,
x=11 or x=-2
