$m^2+21=m$
Learn how to solve integral calculus problems step by step online. Find the roots of m^2+21=m. Find the roots of the equation using the Quadratic Formula. Grouping all terms to the left side of the equation. 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=-1 and c=21. 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.
