$-2x^2+x-1=0$
Learn how to solve equations problems step by step online. Find the roots of -2x^2+x+-1=0. Find the roots of the equation using the Quadratic Formula. 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}.
