$2x^2-x-1\cdot -1=0$

Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation -2x^2+x-1=0. For a simpler handling of the equation, change the sign of all terms, multiplying the entire whole by -1. Multiply -1 times -1. To find the roots of a polynomial of the form ax^2+bx+c we use the quadratic formula, where in this case a=2, b=-1 and c=1. Then substitute the values of the coefficients of the equation in the quadratic formula: \displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}. Simplify \frac{-1\cdot -1\pm \sqrt{{\left(-1\right)}^2-4\cdot 2\cdot 1}}{2\cdot 2}.

$x=\frac{1+2.645751i}{4},\:x=\frac{1-2.645751i}{4}$
