Question

-x2 - 3x + 1 = 0

Answer 1

what?

Answer 2

I don't know how to solve it

Answer 3

oh wait

Answer 4

you could use quadratic formula

Answer 5

x= -b±√b²-4ac/2a
3±√-3²-4(-1)(1)/2(-1)
3±√5/-2

Answer 6

what are you answer choices

Answer 7

Multiply by -1 on both sides

Answer 8

use quadratic formula.

Answer 9

Multiplying by -1 was a good idea. It doesn't solve anything, but it makes the problem look more like things usually look.

\[ \LARGE x^2 + 3x - 1 = 0\]

Now you have several choices as have been suggested. You can use the quadratic formula, you can complete the square, in this case you probably cannot factor it by inspection, but that is something you could try in other problems.
