$$m\left(m-1\right)$$

Steps Using the Quadratic Formula

Quadratic polynomial can be factored using the transformation ax^{2}+bx+c=a\left(x-x_{1}\right)\left(x-x_{2}\right), where x_{1} and x_{2} are the solutions of the quadratic equation ax^{2}+bx+c=0.

$$m^{2}-m=0$$

All equations of the form ax^{2}+bx+c=0 can be solved using the quadratic formula: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.

$$m=\frac{-\left(-1\right)±\sqrt{1}}{2}$$

Take the square root of 1.

$$m=\frac{-\left(-1\right)±1}{2}$$

The opposite of -1 is 1.

$$m=\frac{1±1}{2}$$

Now solve the equation m=\frac{1±1}{2} when ± is plus. Add 1 to 1.

$$m=\frac{2}{2}$$

Divide 2 by 2.

$$m=1$$

Now solve the equation m=\frac{1±1}{2} when ± is minus. Subtract 1 from 1.

$$m=\frac{0}{2}$$

Divide 0 by 2.

$$m=0$$

Factor the original expression using ax^{2}+bx+c=a\left(x-x_{1}\right)\left(x-x_{2}\right). Substitute 1 for x_{1} and 0 for x_{2}.

$$m^{2}-m=\left(m-1\right)m$$

Evaluate

$$m\left(m-1\right)$$
