Answer:

The correct option is 2 and the solutions of given equation are irrational.

Step-by-step explanation:

The given equation is

[tex]3x^2-x-5=0[/tex]

If an equation is defined as

[tex]ax^2+bx+c=0[/tex]

Then the quadratic formula is

[tex]x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

The value of discriminant for the given equation is

[tex]x=\frac{-(-1)\pm \sqrt{(-1)^2-4(3)(-5)}}{2(3)}[/tex]

[tex]x=\frac{1\pm \sqrt{61}}{6}[/tex]

Since [tex]\sqrt{61}[/tex] is an irrational number, therefore the addition and division with an irrational number is irrational.

So, both the solutions of given equation are irrational and option 2 is correct.

Answer:

B: 2 irrational solutions
