Solve -6x^2+6x

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

Factor

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

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.

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

Take the square root of 6^{2}.

$$x=\frac{-6±6}{2\left(-6\right)}$$

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.

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

Divide 0 by -12.

$$x=0$$

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

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

Divide -12 by -12.

$$x=1$$

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

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

Evaluate

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