Answer 1

Answer:

Does anyone know how to do this?

Step-by-step explanation:

Answer 2

Answer:

$\frac{-2\pm\sqrt{70}}{6}}$

Step-by-step explanation:

The quadratic formula is $\frac{-b\pm\sqrt{b^2-4ac}}{2a}$, where a, b, and c are values in the quadratic ax^2 + bx + c. Plug in the values to get $\frac{-4\pm\sqrt{4^2-4(6)(-11)}}{2\cdot6} \implies \frac{-4\pm\sqrt{16+264}}{12} \implies \frac{-4\pm2\sqrt{70}}{12} = \boxed{\frac{-2\pm\sqrt{70}}{6}}$
