Dafna11 [192]
Do you need the answer from the quadratic formula? if so:
\frac{b+/- \sqrt{-b^2-4(a)(c)} }{2(a)}
x^2=a
-3x=b
-18=c

\frac{3+/- \sqrt{3^2-4(1)(-18)} }{2(1)}

\frac{3+/- \sqrt{9+72} }{2}

\frac{3+/- \sqrt{81} }{2}

\frac{3+/- 9 }{2}

\frac{3+9}{2}=  \frac{12}{2} =6

\frac{3-9}{2} = \frac{-6}{2} =-3

Your answer would then be 6 and -3
