Question

NEED HELP ASAP PLZ!!!!!! If the quadratic formula is used to find the solution set of 3x 2 + 4x - 2 = 0, what are the solutions?

Answer 1

Answer:

The solution of the given equation are $x=\frac{-2-\sqrt{10}}{3}$ and $x=\frac{-2+\sqrt{10}}{3}$.

Step-by-step explanation:

If a quadratic equation is $ax^2+bx+c=0$, then the quadratic formula is

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

The given quadratic equation is

$3x^2+4x-2=0$

Here, $a=3,b=4,c=-2$

Using quadratic formula, we get

$x=\frac{-4\pm \sqrt{4^2-4(3)(-2)}}{2(3)}$

$x=\frac{-4\pm \sqrt{40}}{6}$

$x=\frac{-4\pm 2\sqrt{10}}{6}$

$x=\frac{-2\pm \sqrt{10}}{3}$

Therefore the solution of the given equation are $x=\frac{-2-\sqrt{10}}{3}$ and $x=\frac{-2+\sqrt{10}}{3}$.

Answer 2

I think the answer is (-2-\sqrt(10))/(3) 
i know that looks wierd...sorry...i hope this helps
