$-\left(-1\right)x^2-6x-8=0$

Learn how to solve quadratic equations problems step by step online. Solve the quadratic equation -x^2+6x+8=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=1, b=-6 and c=-8. Then substitute the values of the coefficients of the equation in the quadratic formula: \displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}. Simplifying.

##  Final answer to the problem

$x=7.1231056,\:x=-1.1231056$
