A. {0.4, 5.6}
B. {0.5, 4.8}
C. {1.4, 2.4}
D. no real number solution
The answer is D.

Answer 1

answer is
\[3\pm\sqrt{7}\]

Answer 2

so i was correct ?

Answer 3

No the answer is a real number

Answer 4

\[x^2-6x+2=0\]
\[x^2-6x=-2\]
\[(x-3)^2=-2+3^2=-2+9=7\]
\[x-3=\pm\sqrt{7}\]
\[x=3\pm\sqrt{7}\]

Answer 5

so C ?

Answer 6

calculator gives approximations as .35 and 5.6 so it is A
