Question

x^2-3x-2=0 use quadratic formula, by the way, can these be factored instead? im not sure

Answer 1

This one cant be factored without the quadratic formula

Answer 2

No, it can't be factored with integers because there are not pair of integers such that they multiply to (-2) and add to (-3).

Answer 3

you have a quadratic equation on the form ax^2 + bx + c where the quadratic formula is \[\frac{-b \pm \sqrt{b^2-4ac}}{2a}\] Just plug in a, b, and c and simplify

Answer 4

oh, ok thanks Math

Answer 5

3+-sqrt17 over 2? is this right

Answer 6

Yes!! Nicely done!

Answer 7

really? yay :D

Answer 8

yeah its right!! lol
