Question

Solve x2 – 3x = –8
Answer

Answer 1

the square assumed \[x^2-3x=-8\]
add 8 to each side of the =
\[x^2-3x+8=0\]
then..

Answer 2

factoring isn't simple, so you can use the quadratic equation.

Answer 3

do you know it?

Answer 4

no but theres for muti choice questions want me to send them then maybe you can figure it out ? cuz i dony get at all

Answer 5

*four * dont

Answer 6

\[x = \frac{-b \pm \sqrt(b^2-4*a*c)}{2*a}\]

Answer 7

\[x^2−3x+8=0\]
\[x=\frac{-b \pm \sqrt{b^2-4*a*c}}{2*a} = x=\frac{-(-3) \pm \sqrt{(-3)^2-4*1*8}}{2*1}\]

Answer 8

\[x=\frac{3 \pm \sqrt{9-32}}{2}\]

Answer 9

\[x=\frac{3 \pm \sqrt{-23}}{2}\]

Answer 10

Then they pulled out the \[\sqrt{-1} = i\]

Answer 11

does that help any? confused anywhere?

Answer 12

so file called choice 2 is likely it.

Answer 13

thank you

Answer 14
