$x^2-2x-16=0$
Learn how to solve quadratic formula problems step by step online. Solve the quadratic equation x^2-2x+-8+-8=0. Subtract the values -8 and -8. 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=-2 and c=-16. 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. To obtain the two solutions, divide the equation in two equations, one when \pm is positive (+), and another when \pm is negative (-).
