Question

Identify the solutions of 3x2 - x - 4 = 0.
Answer

Answer 1

that is the quadratic equation... do you know its formula ? :)

Answer 2

not really

Answer 3

\[\LARGE x_{1/2}=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\]
\[\LARGE ax^2+bx+c=0\]
in your case you have:
a=3
b=-1
c=-4
substitute in this formula:
\[\LARGE x_{1/2}=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\]
and there you go... :) can you do it ?

Answer 4

yep got it thanks
