WebThe ABC Formula. Another way to find the roots of a quadratic function. This is an easy method that anyone can use. It is just a formula you can fill in that gives you roots. The formula is as follows for a quadratic function ax^2 + bx + c: (-b + sqrt (b^2 -4ac))/2a and (-b - sqrt (b^2 -4ac))/2a. These formulas give both roots. Web1 g ( x) = 1 − ln x − x 2 → g ′ ( x) = − ( 1 x + 2 x) < 0 for any x > 0. But we also know that g ( 1 / e) = 2 − 1 / e 2 > 0; g ( 1) = 0 g is decreasing because g ′ ( x) < 0. It means that x = 1 is the only one roots of g ( x). Without using a numerical method you can't find the roots.
