Use the quadratic equation to solve this
Remember that quadratic functions are set up like so:
[tex]ax^{2} +bx +c = 0[/tex]
That means that in this equation...
a = -3
b = -18
c = -35
^^^Plug these numbers into the quadratic equation and solve...
[tex]\frac{18+/-\sqrt{(-18)^{2}-4(-3)(-35)}}{2(-3)}[/tex]
[tex]\frac{18 +/-\sqrt{324+(-420)}}{-6}[/tex]
[tex]\frac{18+/-\sqrt{-96} }{-6}[/tex]
[tex]\frac{18+/4i\sqrt{6} }{-6}[/tex]
[tex]\frac{-9+/-2i\sqrt{6} }{3}[/tex]
Keep in mind that +/- is ±
[tex]\frac{-9+2i\sqrt{6} }{3}[/tex]
[tex]\frac{-9-2i\sqrt{6} }{3}[/tex]
^^^Exact answers
Hope this helped!
