Hello!

The answer is:

$x1=0.53\\x2=-0.17$

Why?

The quadratic formula is:

$x=\frac{-b+-\sqrt{b^{2}-4*a*c } }{2*a}$

We have that:

$a=11\\b=-4\\c=-1$

By substituting we have:

$x=\frac{4+-\sqrt{-4^{2}-4*11*-1 } }{2*11}=\frac{4+-\sqrt{16+44} }{22}=\frac{4+-\sqrt{60} }{22}=\frac{4+-(7.75)}{22}$

$x1=\frac{4+7.75}{22}=0.53\\\\x2=\frac{4-7.75}{22} =-0.17$

Have a nice day!
