The solutions to the equation are
(2 +/- √(15)))/(11).

You can find the answer to any quadratic by using the quadratic formula. The formula is below.


\frac{-b +/- \sqrt{b^(2)-4ac}}{2a}

Then find a (the number attached to x^2), b (the number attached to x) and c (the constant). This will allow you to plug in and solve.


\frac{4 +/- \sqrt{-4^(2)-4(11)(-1)}}{2(11)}


(4 +/- √(16 + 44))/(22)


(4 +/- √(60)))/(22)


(2 +/- √(15)))/(11)
