Solve 6x^2-6x

$$6 x ^ { 2 } - 6 x$$

Factor

$$6x\left(x-1\right)$$

Solution Steps

Factor out 6.

$$6\left(x^{2}-x\right)$$

Consider x^{2}-x. Factor out x.

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

Rewrite the complete factored expression.

$$6x\left(x-1\right)$$

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.

$$6x^{2}-6x=0$$

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.

$$x=\frac{-\left(-6\right)±\sqrt{\left(-6\right)^{2}}}{2\times 6}$$

Take the square root of \left(-6\right)^{2}.

$$x=\frac{-\left(-6\right)±6}{2\times 6}$$

The opposite of -6 is 6.

$$x=\frac{6±6}{2\times 6}$$

Multiply 2 times 6.

$$x=\frac{6±6}{12}$$

Now solve the equation x=\frac{6±6}{12} when ± is plus. Add 6 to 6.

$$x=\frac{12}{12}$$

Divide 12 by 12.

$$x=1$$

Now solve the equation x=\frac{6±6}{12} when ± is minus. Subtract 6 from 6.

$$x=\frac{0}{12}$$

Divide 0 by 12.

$$x=0$$

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}.

$$6x^{2}-6x=6\left(x-1\right)x$$

Evaluate

$$6x\left(x-1\right)$$
